TUOPMA04	Apple II Insertion Devices Made at MAXIV	undulator, alignment, operation, polarization	6
	A. Thiel, M. Ebbeni, H. Tarawneh MAX IV Laboratory, Lund University, Lund, Sweden
	At present five Apple II insertion devices were made and installed at MAX IV, three of them in the 1.5GeV-ring, and two in the 3GeV-ring. The assembly of the last one of a total number of six Apple II undulators made at MAX IV is currently going on. The undulators have period lengths of 48mm (two devices), 53mm, 58mm, 84mm and 95.2mm. The operational gap range of the 3GeV devices is between 11mm and 150mm, the range of the 1.5GeV devices is 14mm to 150mm. Structural analysis was applied to assure a minimum deflection of the main frame and the magnet array girders. The main frame is made of nodular cast iron, while the girders are made of aluminium alloy. In order to optimize the magnetic tuning the position of the magnet keepers can be adjusted by wedges. The undulators were fiducialized before the installation in the ring tunnel and were aligned in the straight section using their magnetic centre as reference. All MAX IV made undulators have three feet with vertical adjustment and separate horizontal adjusters. This paper describes the design, assembly, shimming and installation of the MAX IV Apple II devices in more detail.

	Funding: Work supported by DOE under contract DE-SC0012704 A 2.8 m long quasi-periodic APPLE II type undulator has been commissioned at the National Synchrotron Light Source II (NSLS-II) for the Electron Spectro-Microscopy (ESM) beamline in the framework of the NEXT (NSLS-II Experimental Tools) project. It provides high brilliance photon beams in circularly and linearly polarized radiation from VUV to soft X-Rays. The mechanical structure implemented to achieve the quasi-periodicity in the magnetic field profile is described together with the optimization techniques utilized to correct the undesirable phase-dependent errors. The final magnetic results are presented as well as the spectral performance of the device. Although this EPU (Elliptically Polarizing Undulator) was procured as a turn-key device, the vendor was only responsible for the mechanical frame and the control system. Sorting and assembly of the magnet modules and the magnetic field tuning - Virtual Shimming and Magic Finger - were performed at the NSLS-II Magnetic Measurement Lab.

TUPH30	ALBA Synchrotron Light Source Liquefaction Helium Plant	operation, synchrotron, experiment, ECR	102
	M. Prieto, J.J. Casas, C. Colldelram, Y. Nikitin ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	ALBA is a 3rd generation Synchrotron Light facility with: 8 operational Beam Lines (BLs), a 2nd BL of Phase II under construction and 3 first Phase III BLs in design phase. Some user experiments require Liquid Helium (LHe) as a coolant. The resulting LHe consumption at ALBA is about 650 l/week. Thus far the vaporized helium, which results from the refrigeration of experiments and equipment, has been released into the atmosphere without being reused. Due to the increasing price of LHe, ALBA agreed with ICN2 (Catalan Institute of Nanoscience and Nanotechnology) to invest in a Liquefaction Helium Plant. Internal staff has carried out the project, installation and pressure equipment legalization of the plant, which is located in a new 80 m2 construction. Under operation the plant allows recycling up to 24960 litres of LHe per year, which is an 80% of the helium consumed at ALBA, by making the gaseous helium undergo through 3 main stages: recovery, purification and liquefaction. The plant, unique in Catalonia, will entail cost savings about 77% and will reduce vulnerability to supply disruptions. ICN2 will benefit from a part of the production due to their initial investment.

WEPH06	Upgrade of Magnetic Measurements Laboratory at ALBA Synchrotron	controls, hardware, software, TANGO	211
	J. Campmany, F. Becheri, J. Marcos, V. Massana, R. Petrocelli, L. Ribó ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	Along 2017 and 2018, a complete upgrade of ALBA magnetic measurements lab has been done. Upgrade has affected both hardware and software. Regarding hardware, a relevant innovation has been the replacement of DC motors by step motors in new Hall probe bench and in flipping and rotating coil benches. Up to now, this kind of continuous measurements usually were done using DC motors because step motors were considered unable to fulfil the required smoothness of the movement. However, current step motors state of the art made them compatible with DC. In our case, we have tested the performance of upgraded benches and they reach the same accuracy, or even better. Regarding software, we have unified all motion drivers to ICEPAP and all control system to Tango package, taking advantage of the last ICEPAP firmware. That includes the feature of triggering data acquisition system by signals generated from different axis that can be selected by software.

	Funding: Ministry of Science, Technology, Innovation and Communication (MCTIC) A Front End (FE) prototype for a 19-mm period length Adjustable Phase Undulator (APU19) beamline of the new Brazilian 4th-generation synchrotron, Sirius, was assembled in the LNLS metrology building in January 2017 to validate main design concepts. Regarding stability, flow-induced vibration (FIV) investigations were carried out on the water-cooled components, and modal analyses were made on the X-Ray Beam Position Monitor (XBPM) support. As for the vacuum system, final pressure levels were investigated and a vacuum breach was intentionally provoked to verify the performance of the equipment protection system (EPS). In addition, cycling tests of the Photon and Gamma shutters were conducted to verify the FE reliability. Moreover, the three-layer protection system, developed to limit the maximum aperture for the high-power slits, was functionally evaluated. Finally, the results were used to improve the FE to its final design. This paper describes the tests setups and results obtained during the validations.

THPH02	LCLS Pulse Selector, A Multifunction Shutter for the LCLS-I 120 Hz FEL	controls, timing, operation, FEL	336
	R. Armenta, E.A. Paiser SLAC, Menlo Park, California, USA
	The LCLS Pulse Selector was designed to pick specific pulses and reduce the repetition rate of the 120Hz LCLS pulse train in support of widely diverse, user defined experiments. It utilizes two rotating parallel plates to alternately transmit and block pulses in a single sweeping motion. A conventional stepper motor connected to the plates provides the rotation. The key to the system is its sophisticated timing scheme. Each sweep of the shutter is synchronized (with a precise delay) with the event codes normally generated with each pulse for data acquisition use. This shutter system has the capability of reducing the repetition rate of the LCLS x-ray to any frequency less than or equal to 60Hz in order to select a single pulse of LCLS x-ray beam at 120Hz. Since its installation, the pulse selector has been used in multiple experiments with great success providing independent pulse selection to individual beamlines at the same time.

	Funding: This research used resources of the Advanced Light Source, which is a DOE Office of Science User Facility under contract no. DE-AC02-05CH11231. The Advanced Light Source has developed a compact tomographic microscope based on soft x-ray ptychography for the study of meso and nanoscale materials [1,2]. The microscope utilizes the sample manipulator mechanism from a commercial TEM coupled with laser interferometric feedback for zone plate positioning and a fast frame rate charge-coupled device detector for soft x-ray diffraction measurements. The microscope has achieved scan rates of greater than 50 Hz, including motor move, data readout and x-ray exposure, with a positioning accuracy of better than 2 nm RMS and has achieved spatial resolution of better than 5 nm. The instrument enables the use of commercially available sample holders compatible with FEI TEMs. This allows in-situ measurement of samples using both soft x-rays and electrons. This instrument is a refinement of a currently commissioned instrument called The Nanosurveyor, which has demonstrated resolution of better than 20nm in both two and three dimensions using 750 eV x-rays. [3] The instrument has been installed on the new COSMIC beamline at the ALS. It will enable spectromicroscopy and tomography of materials with wavelength limited spatial resolution. [1] P.
