	R. Veness, W. Andreazza, D. Gudkov, A. Miarnau Marin, S. Samuelsson CERN, Geneva, Switzerland
	3D additive machining by selective laser melting (SLM) has great potential for widespread use in the field of accelerator instrumentation. However, as with any new process or material, it must be adapted and qualified for use in the specific in-vacuum accelerator environment. This paper outlines recent developments of this technology for beam instrumentation in CERN accelerators. It covers topological optimisation, design and production methods for SLM, validation and test of samples and components to qualify the production process. It also reports on experience of operation in multiple machines with beam.

TUPH43	The LNLS Metrology Building - Environmental Control Results	controls, optics, synchrotron, operation	143
	H.G.P. de Oliveira, C.S.N.C. Bueno, L. Sanfelici, M.B. da Silva LNLS, Campinas, Brazil
	Funding: Ministry of Science, Technology, Innovation and Communication (MCTIC) Modern synchrotron light sources require high mechanical stability throughout its facilities, frequently demanding characterization processes in theμand nanometer scales. In this context, the Brazilian Synchrotron Light Laboratory (LNLS) built a new facility with several controlled environment rooms to minimize disturbances during optical and mechanical metrology procedures and to support advanced instrumentation development for the new Sirius' beamlines. The building design imposed very strict requirements regarding temperature, humidity and particles. This work presents the environmental control validation results and the floor vibration assessment enlightening the influence of the building machinery. Temperature variations below ± 0,1 °C were successfully achieved for all rooms, relative humidity is also better than 50 ± 5 % and the floor RMS displacement did not exceed 15 nm. The building is fully operational since early 2017 and currently hosting several tests on monochromators, mirrors, front-ends and many other systems for the Sirius beamlines. Metrology, environmental control, vibration assessment

WEPH01	Evaluation of Anisotropic Simulations & Redesign of the BXDS High Energy Monochromator Bent Laue Diffraction Crystal Holders	focusing, simulation, radiation, wiggler	199
	M.J.P. Adam, N. Appathurai CLS, Saskatoon, Saskatchewan, Canada
	The Brockhouse X-ray Diffraction and Scattering Sector (BXDS) High-Energy (HE) beamline includes a bent Laue diffraction monochromator. The BXDS HE monochromator achieves energy ranges of 35keV to 90 keV through the bent Laue diffraction of two silicon crystal wafers. Each wafer (460um & 1000um thick) is bent to achieve specific sagittal radius (Rs); subsequent anticlastic meridional radius (Rm) results from the anisotropic nature of silicon, creating the desired x-ray focusing parameters. During the initial conditioning of the BXDS HE monochromator spurious diffraction patterns were observed indicating that the crystal holder, and crystal integrity failed. Alternative holder designs were evaluated using Finite Element Analysis (FEA; ANSYS) simulations to ensure that appropriate Rs and Rm values were achieved, verification of the crystal holder Rs was completed using contact 3D measurement (FaroArm), and the crystal surface was assessed using 3D optical profiling (Zygo). A superior holder was chosen based on the results, and replaced. The performance of the BXDS HE monochromator has been characterized, indicating the new holder design has achieved x-ray focusing parameters.

WEPH03	Design of New Beam Instrumentation for the ISOLDE Isotope Separator at CERN	ISOL, vacuum, electronics, electron	205
	W. Andreazza, M. Duraffourg, G.J. Focker, A. Miarnau Marin, D. Smakulska, J. Tassan-Viol, R. Veness CERN, Geneva, Switzerland
	The ISOLDE radioactive ion beam separator facility at CERN produces beams of short-lived isotopes for experiments in physics, material and medical science. New requirements for more precise measurement of profile, position and intensity has pushed the CERN beam instrumentation group to start the study of a new generation of ISOLDE beam instrumentation dedicated to the specific needs of this facility. This paper will describe the design and the development of a number of new ISOLDE instruments with the aim of achieving better performance, increased reliability and to facilitate maintenance in the radioactive environment. It will explain how modern technologies (i.e. magnetically coupled push pull, 3D additive machining) have been used to make a modern, precise and reliable beam instrumentation design.

WEPH21	A Family of Redundant Positioning Devices for Synchrotron Applications	synchrotron, GUI, scattering	249
	G. Olea, N. Huber HUBER Diffraktiontechnik GmbH&Co.KG, Rimsting, Germany
	A family of reconfigurable devices able to work in synchrotron applications, especially in diffractometer environments has been developed. It can provide six (6) or less than six (<6) degrees of freedom (dof) motion capabilities (F<=6) being able to pose a heavy load sample (instruments) with high precision towards an X-ray coming beam. It is based on the Parallel Kinematics (PK) Quatropod concept with redundant actuation (Rd=2) and were built around the fully (F=6dof) basic topology 6-4(213) where 2-actuated and 1, 3-passive joints, respectively. By altering the passive joints dof, structures with less than six dof (F<6) can be obtained, e.g. 5-4[213(2)]/F=5, 4-4[213(1)]/F=4, 3-4[213(0)]/F=3 (3(2) and 3(1)and 3(0) stand for 3dof joint with constrained(less) dof - f=2, 1 or 0/blocked). For a perfect symmetric arrangement and using only P and S (P-prismatic, S-spherical) joints, several useful positioning mechanisms are presented. And, in the design phase, 2dof linear actuators(2P), e.g. XY stages have been proved to be a suitable choice, too. * J.P. Merlet, Parallel Robots Springer (2ed), 2006 G.

	PROXIMA 2A is a high performance 3rd generation synchrotron beamline dedicated to X-ray micro-crystallography on biological macromolecules. Since opening in March 2013, the experimental station has hosted a large number of users who have collected vast amounts of X-ray diffraction images from literally thousands of crystals. In order to streamline the throughput, enhance performance and add functionality, a number of innovative developments have been launched on PROXIMA 2A. These cover all aspects of the beamline, from the practical to the visionary: such as the design, fabrication and implementation of a dedicated high-precision motorized stage to screen crystallization plates for in situ X-ray data collections, and the employment artificial intelligence and computer vision technologies for the detection of samples under liquid nitrogen. Other notable beamline projects include the addition of a vertical translation table for the EIGER X 9M detector to permit the acquisition of ultrahigh (0.6 Å) resolution X-ray data, the incorporation of a miniaturized YAG-coupled photodiode within a beamstop and the determination of the SOC of a recently added kappa arm to the goniometer.
