TUPE01	DMM Thermal Mechanical Design	ion, optics, operation, experiment	152
	J.H. Kelly DLS, Oxfordshire, United Kingdom
	A Double Multilayer Monochromator (DMM) was designed in-house for the VMXi beamline. Thermal mechanical finite element analysis was performed to design a novel optic geometry, employing In/Ga eutectic cooling. The integration of a DMM into the existing beamline required additional power management components, such as a low energy power filter, a power detector and compact CuCrZr masks. This paper describes the thermal management challenges and their solutions. The DMM has been fully commissioned and is operational within the original I02 beamline.

TUPE18	Design and FEA of a 3D Printed Detector Window Frame	ion, scattering, vacuum, experiment	201
	W. Tizzano DLS, Oxfordshire, United Kingdom
	The purpose of the project was to design and simulate a window assembly to be used in GISAX/GIWAX experiments. The window lies between the sample and the WAXS detector, a modified, in-vacuum detector, with modules removed to allow scattered radiation to pass through to a SAXS* detector positioned downstream. The window uses 75um thick Kapton HN film and given the size, pressure and the short distance to the sensors, it was necessary to support it on a frame. To avoid any information loss from shadowing of the detector, a frame was designed so that shadows will be projected into the gaps between the detector modules. The geometry was such that DMLS**** was an effective way of producing the item. Given the slenderness of the structure and the forces it supports, the material approaches or exceeds its yield point, so a bilinear, isotropic, hardening material model was chosen; moreover, large deflections were enabled. Also, the contacts were modelled with augmented Lagrange frictional formulation. All these assumptions made the analysis strongly non-linear.

WEAA04	Novel Numerical Method for Calculating the Shadow Projection and Collisions of a Multi-Axis Goniometer at Diamond	ion, vacuum, factory, alignment	267
	V. Grama, A. Wagner DLS, Oxfordshire, United Kingdom
	Beamline I23 is a long-wavelength macromolecular crystallography beamline at Diamond Light Source. The end station is a unique instrument with a bespoke cryogenically cooled multi-axis goniometer and a large curved Pilatus 12M detector in a high vacuum environment. As experiments become limited by radiation damage to the crystals, optimised strategies are needed to orient crystals in the most efficient way to obtain a complete dataset with a minimal X-ray dose. Two key factors affect the optimisation strategies. Firstly, shadowing on the detector by the goniometer resulting in data loss in this region and secondly, collisions between the goniometer and other components in the end station restricting the available angular range for sample centering and data collection. This paper discusses the numerical methods for calculating the shadowing of a multi-axis goniometer on a semi-cylindrical detector and the calculation of the allowable angles for various conditions to prevent collisions with neighbouring components.

WEPE10	Mechanical Design of Pulse-by-Pulse X-Ray Beam Position Monitor Using Diamond Heat Sink	ion, radiation, cathode, synchrotron-radiation	333
	H. Aoyagi, S. Takahashi JASRI/SPring-8, Hyogo, Japan
	Funding: This work was partly supported by Japan Society for the Promotion of Science through a Grant-in-Aid for Scientific Research(c), No.20416374. The pulse-by-pulse X-ray beam monitor equipped with microstripline structure had been developed at SPring-8. This monitor has a potential to function as (1) a pulse intensity monitor, (2) a pulse-by-pulse X-ray beam position monitor (XBPM), and (3) a pulse timing monitor. In insertion device beamlines, however, it cannot be used without further improvement because of heat-resistance problem. Therefore, we examined a pulse-by-pulse XBPM for insertion device beamlines by introducing heat resistance structure, which employed a diamond heat sink. Thermal finite element analysis was carried out to design an effective structure of a detector head and the holder. Evaluation tests of the prototype will be also presented in this contribution.

WEPE28	Minimizing Experimental Setup Time and Effort at Aps Beamline 1-Id Through Instrumentation Design	ion, instrumentation, experiment, alignment	353
	E. Benda, J. Almer, P. Kenesei, A. Mashayekhi, J.S. Okasinski, J.S. Park, R. Ranay, S.D. Shastri ANL, Argonne, Illinois, USA
	Sector 1-ID at the APS accommodates a number of different experimental techniques in the same spatial envelope of the E-hutch end station. These include high energy small and wide angle x-ray scattering (SAXS and WAXS), high energy diffraction microscopy (HEDM, both near and far field modes) and X-ray tomography. These techniques are frequently combined to allow the users to obtain multimodal data with 1 um spatial resolution and 0.05° angular resolution. Furthermore, these techniques are utilized while the sample is thermo-mechanically loaded to mimic real operating conditions. The instrumentation required for each of these techniques has been designed and configured in a modular way with a focus on stability and repeatability between changeovers. This not only allows the end station to be used for a greater number of techniques but it also results in a reduction of time and effort typically required for set up and alignment. Key instrumentation design features and layout of the end station are presented.

WEPE29	A Novel Filter Auto-Mounter for the BioXAS Beamlines at the CLS	ion, software, MMI, experiment	357
	S.R. Carriere, D. Beauregard, B.A. Schneider, G.A. Steel, D.M. Taylor CLS, Saskatoon, Saskatchewan, Canada
	Funding: Canadian Foundation for Innovation The BioXAS beam-lines are a recently completed group of beam-lines at the Canadian Light Source (CLS). The BioXAS EXAFS beam-lines host three 32-element germanium detectors. There was a need to introduce an exchangeable filter between the soller slits and the 32-element germanium detectors. It was further required to have an automated filter exchange system so that users could quickly vary filter thicknesses and types to determine the effect on the signal. An auto-mounting filter system was created to meet these requirements and allows users to quickly exchange filters without breaking experimental hutch lockup. The auto-mounter cartridge can hold up to ten slides that measure 100mm X 55mm in cross-section. The device inserts slides in an extremely small envelope between the soller slits and the liquid helium cryostat. The auto-mounter assembly also houses the stages required to actuate the soller slits laterally and vertically. During device commissioning we performed 800 consecutive successful filter exchanges as part of a stress test. The spatial constraints, mechanics, and fabrication of the device will be presented. Software development will also be discussed.

WEPE37	Upgrade of the Super Advanced X-Ray Spectrometer (SAXES) of the RIXS Endstation for Better Resolution and Larger Detector Size	ion, vacuum, GUI, scattering	367
	St. Maag, P. Hirschi, L. Nue, T. Schmitt, X. Wang PSI, Villigen PSI, Switzerland
	The RIXS endstation of ADRESS beamline at Swiss Light Source (SLS) is equipped with an ultrahigh resolution X-ray spectrometer. The spectrometer with a length of 5 m is installed on a rotating girder platform and allows varying scattering angles from 30° to 130°. The position of the CCD detector is longitudinally adjustable on the girder and vertically adjustable on a moving frame to allow an angle between 2° to 15° in the vertical plane. In the scope of a CCD camera upgrade, the modification of the vertical alignment of the guiding structure and ultra-high vacuum tanks became necessary. The new camera with a higher resolution and larger detector size weights around 25 kg. It is required to have a vibration amplitude well below 2 micrometer. We will present the critical design parameters of the upgrade, and the effort to increase bending stiffness of vacuum guide structure while keeping major geometry parameters. In addition, kinematic overdeterminacy was removed. After the upgrade we performed vibration measurements verifying that dynamic stability of the camera is improved, and design goal is reached. The site acceptance test confirmed the proper operation of the new mechanism.

WEPE38	The Mechanics of the Vekmag Experiment	ion, experiment, GUI, scattering	370
	T. Noll MBI, Berlin, Germany F. Radu HZB, Berlin, Germany
	For the experiments at synchrotron radiation source BESSY II synchrotron of the Helmholtz-Zentrum Berlin a new end station and a new beam-line were developed and are now in user operation. The end station contains a 9-2-1 Tesla vectorial magnet and a cryostat with manipulator for the sample cooling and positioning, an UHV deposition chamber, and an UHV detector chamber. We report here on the technical design of the detector chamber which is placed below the magnet chamber and is also connected to the deposition chamber. Because of various constrains a sophisticated mechanics had to be developed to provide integrated functionality for both the detector holder and the sample transfer units. The detector unit consists of a tubular holder of 5 cm diameter which travels more than 60 cm vertically and exhibits an unlimited rotation degree of freedom of 360 degrees within the magnet bore. The sample transfer unit consists of a telescopic movement mechanism allowing for the sample holder vertical travel within the detector tubular holder. The functionality challenges and their resolve were addressed in an innovative mechanical design.

WEPE40	Two-rotation Mechanism for an in Vacuum Beamstop	ion, vacuum, scattering, experiment	378
	J.B. González Fernández, C. Colldelram, A. Fontserè Recuenco, G. Jover-Mañas, J. Ladrera Fernández, M. Malfois, J.C. Martínez Guil ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	At Small-angle X-ray Scattering beamlines (SAXS), beamstops are needed to block the intense primary beam that has not been scattered by the sample in order to protect the detector from any damage. Beamstops are usually confined inside a vacuum tube minimizing air space between the sample and the detector. For certain experiments, a motorized beamstop is required to achieve a precise positioning in different regions of the detector active area. ALBA has developed a new motorized beamstop* consisting of a two-rotation mechanism inside vacuum that composes a movement able to cover all range of the active area of the detector. The presented solution involves a main rotation reached by a gear and a worm drive actuated by a stepper motor and a second rotation relative to the main one produced by a piezo rotation stage. For each position appears two different solutions. This characteristic permits take two equivalent images in the detector with the same beamstop position but different orientation in the beamstop support; thus permitting the compensation of the support shadow on the active area of the detector. * Patent Registered

THAA04	Upgrading a Transmission SAX/WAX Beamline to Allow High Quality GISAX/GIWAX Experiments for Soft Matter Thin Films	ion, vacuum, scattering, alignment	390
	A.R. Marshall DLS, Oxfordshire, United Kingdom
	The project required a sample environment to deliver experiments in vacuum or helium, with high humidity, including capacity to use aggressive solvents. The compact, transportable system incorporates a high precision in-vacuum manipulator/ positioning stage (with repeatability better than1 µm/ 1 mdeg) allowing for multiple sample configurations. Current sample mounts include in-situ film formation (Doctor Blade), thermal annealing/drying heater stage, sample cooling and multiple sample stages; the system has been designed to accommodate many sample substrate formats. The existing end station camera system has been upgraded to include two, in-vacuum, WAXS and SAXS area detectors, which are custom builds based on the Pilatus 6M. The SAX detector module includes three in vacuum, independent ,configurable SAXS beam stop manipulators to block GISAXS transmitted, reflected and specular flare as well as isotropic and anisotropic SAX, a photon sensitive detector shutter plate is included. The 4 mm diameter tungsten beamstops each include a miniature photodiode to measure beam intensity and can be positioned to within 10 µm precision in X and Y over 300 mm x 250 mm motion range.

FRAA01	Engineering Challenges on the I14 Nanoprobe Beamline	ion, vacuum, optics, cryogenics	398
	A. Peach, F. Cacho-Nerin, J. Parker, P.D. Quinn DLS, Oxfordshire, United Kingdom
	An overview of the double branch 185m I14 Nano-probe beam-line under construction at DLS will be presented together with the end-station design in further detail. The end station consists of a split vacuum vessel containing a KB mirror configuration (at UHV) and the sample environment (at HV) which is just 50mm from the end of the final KB optic. An in-vacuum detector is mounted between the KB and the sample whilst two externally mounted detectors will operate between 0.25m & 3m from the sample. Four cryogenic samples can be brought into the vessel at a time and transferred remotely to the sample position with cooling provided by a Helium pulse tube cooler. With an initial 50nm size beam, stability is absolutely critical and careful attention has been paid in the design to mitigate any thermal and structural sources of vibration. An array of interferometers reference the KB mirrors and sample position and will be used to actively correct for any drifts. The very tight space constraints involved have greatly increased the complexity and duration of the design but testing of prototypes is now underway. The system is scheduled for build and test through the Autumn 2016.

This monitor has a potential to function as (1) a pulse intensity monitor, (2) a pulse-by-pulse X-ray beam position monitor (XBPM), and (3) a pulse timing monitor. In insertion device beamlines, however, it cannot be used without further improvement because of heat-resistance problem. Therefore, we examined a pulse-by-pulse XBPM for insertion device beamlines by introducing heat resistance structure, which employed a diamond heat sink. Thermal finite element analysis was carried out to design an effective structure of a detector head and the holder. Evaluation tests of the prototype will be also presented in this contribution.

Sector 1-ID at the APS accommodates a number of different experimental techniques in the same spatial envelope of the E-hutch end station. These include high energy small and wide angle x-ray scattering (SAXS and WAXS), high energy diffraction microscopy (HEDM, both near and far field modes) and X-ray tomography. These techniques are frequently combined to allow the users to obtain multimodal data with 1 um spatial resolution and 0.05° angular resolution. Furthermore, these techniques are utilized while the sample is thermo-mechanically loaded to mimic real operating conditions. The instrumentation required for each of these techniques has been designed and configured in a modular way with a focus on stability and repeatability between changeovers. This not only allows the end station to be used for a greater number of techniques but it also results in a reduction of time and effort typically required for set up and alignment. Key instrumentation design features and layout of the end station are presented.

The BioXAS beam-lines are a recently completed group of beam-lines at the Canadian Light Source (CLS). The BioXAS EXAFS beam-lines host three 32-element germanium detectors. There was a need to introduce an exchangeable filter between the soller slits and the 32-element germanium detectors. It was further required to have an automated filter exchange system so that users could quickly vary filter thicknesses and types to determine the effect on the signal. An auto-mounting filter system was created to meet these requirements and allows users to quickly exchange filters without breaking experimental hutch lockup. The auto-mounter cartridge can hold up to ten slides that measure 100mm X 55mm in cross-section. The device inserts slides in an extremely small envelope between the soller slits and the liquid helium cryostat. The auto-mounter assembly also houses the stages required to actuate the soller slits laterally and vertically. During device commissioning we performed 800 consecutive successful filter exchanges as part of a stress test. The spatial constraints, mechanics, and fabrication of the device will be presented. Software development will also be discussed.

The RIXS endstation of ADRESS beamline at Swiss Light Source (SLS) is equipped with an ultrahigh resolution X-ray spectrometer. The spectrometer with a length of 5 m is installed on a rotating girder platform and allows varying scattering angles from 30° to 130°. The position of the CCD detector is longitudinally adjustable on the girder and vertically adjustable on a moving frame to allow an angle between 2° to 15° in the vertical plane. In the scope of a CCD camera upgrade, the modification of the vertical alignment of the guiding structure and ultra-high vacuum tanks became necessary. The new camera with a higher resolution and larger detector size weights around 25 kg. It is required to have a vibration amplitude well below 2 micrometer. We will present the critical design parameters of the upgrade, and the effort to increase bending stiffness of vacuum guide structure while keeping major geometry parameters. In addition, kinematic overdeterminacy was removed. After the upgrade we performed vibration measurements verifying that dynamic stability of the camera is improved, and design goal is reached. The site acceptance test confirmed the proper operation of the new mechanism.

For the experiments at synchrotron radiation source BESSY II synchrotron of the Helmholtz-Zentrum Berlin a new end station and a new beam-line were developed and are now in user operation. The end station contains a 9-2-1 Tesla vectorial magnet and a cryostat with manipulator for the sample cooling and positioning, an UHV deposition chamber, and an UHV detector chamber. We report here on the technical design of the detector chamber which is placed below the magnet chamber and is also connected to the deposition chamber. Because of various constrains a sophisticated mechanics had to be developed to provide integrated functionality for both the detector holder and the sample transfer units. The detector unit consists of a tubular holder of 5 cm diameter which travels more than 60 cm vertically and exhibits an unlimited rotation degree of freedom of 360 degrees within the magnet bore. The sample transfer unit consists of a telescopic movement mechanism allowing for the sample holder vertical travel within the detector tubular holder. The functionality challenges and their resolve were addressed in an innovative mechanical design.

Two-rotation Mechanism for an in Vacuum Beamstop

At Small-angle X-ray Scattering beamlines (SAXS), beamstops are needed to block the intense primary beam that has not been scattered by the sample in order to protect the detector from any damage. Beamstops are usually confined inside a vacuum tube minimizing air space between the sample and the detector. For certain experiments, a motorized beamstop is required to achieve a precise positioning in different regions of the detector active area. ALBA has developed a new motorized beamstop* consisting of a two-rotation mechanism inside vacuum that composes a movement able to cover all range of the active area of the detector. The presented solution involves a main rotation reached by a gear and a worm drive actuated by a stepper motor and a second rotation relative to the main one produced by a piezo rotation stage. For each position appears two different solutions. This characteristic permits take two equivalent images in the detector with the same beamstop position but different orientation in the beamstop support; thus permitting the compensation of the support shadow on the active area of the detector.

The project required a sample environment to deliver experiments in vacuum or helium, with high humidity, including capacity to use aggressive solvents. The compact, transportable system incorporates a high precision in-vacuum manipulator/ positioning stage (with repeatability better than1 µm/ 1 mdeg) allowing for multiple sample configurations. Current sample mounts include in-situ film formation (Doctor Blade), thermal annealing/drying heater stage, sample cooling and multiple sample stages; the system has been designed to accommodate many sample substrate formats. The existing end station camera system has been upgraded to include two, in-vacuum, WAXS and SAXS area detectors, which are custom builds based on the Pilatus 6M. The SAX detector module includes three in vacuum, independent ,configurable SAXS beam stop manipulators to block GISAXS transmitted, reflected and specular flare as well as isotropic and anisotropic SAX, a photon sensitive detector shutter plate is included. The 4 mm diameter tungsten beamstops each include a miniature photodiode to measure beam intensity and can be positioned to within 10 µm precision in X and Y over 300 mm x 250 mm motion range.

Engineering Challenges on the I14 Nanoprobe Beamline

DLS, Oxfordshire, United Kingdom

An overview of the double branch 185m I14 Nano-probe beam-line under construction at DLS will be presented together with the end-station design in further detail. The end station consists of a split vacuum vessel containing a KB mirror configuration (at UHV) and the sample environment (at HV) which is just 50mm from the end of the final KB optic. An in-vacuum detector is mounted between the KB and the sample whilst two externally mounted detectors will operate between 0.25m & 3m from the sample. Four cryogenic samples can be brought into the vessel at a time and transferred remotely to the sample position with cooling provided by a Helium pulse tube cooler. With an initial 50nm size beam, stability is absolutely critical and careful attention has been paid in the design to mitigate any thermal and structural sources of vibration. An array of interferometers reference the KB mirrors and sample position and will be used to actively correct for any drifts. The very tight space constraints involved have greatly increased the complexity and duration of the design but testing of prototypes is now underway. The system is scheduled for build and test through the Autumn 2016.
