TUPH09	Friction Stir Welding and Copper-Chromium Zirconium: a New Concept for the Design of Sirius' High-Power Absorbers	39
	G.V. Claudiano, P.T. Fonseca, L.M. Volpe LNLS, Campinas, Brazil E.B. Fonseca, M. H. S. Silva LNNano, Campinas, Brazil
	Funding: Ministry of Science, Technology, Innovation and Communication (MCTIC) Sirius, the new Brazilian fourth-generation synchrotron light source, is currently under construction. Due to the high brilliance and low emittance of its source, the pho-ton beam on each undulator beamline can have power densities as high as 55 W/mrad². To protect the compo-nents downstream, the Front-End power absorbers need to manage this power in a limited space, but also having precision in alignment and being reliable all over their lifetime. To achieve this behaviour, the selected alloy was the copper-chromium-zirconium (CuCrZr, commercially known as C18150) because of improved thermal and mechanical properties. In order to seal the vacuum cham-ber (path on which the cooling water flows), friction stir welding was the selected joining method. During the welding process, the material passes through a grain re-finement process which results in a high-resistance joint. The manufacturing process could also result on a reduc-tion of costs and lead times. Finally, it will be presented the final versions of the component with its support and the characterizations done to validate the welded joint under vacuum and water pressure requirements.

TUPH29	Next Generation X-ray Beam Position Monitor System for the Advanced Photon Source MBA Upgrade	99

	Funding: Work supported by the U.S. Department of Energy, Office of Science, under Contract No. DE-AC02-D6CH11357 The Advanced Photon Source (APS) upgrade from double-bend achromats (DBA) to multi-bend achromats (MBA) lattice has increased the need for reliable diagnos-tic systems. This upgrade will decrease the size of the photon beam drastically and beam current will be in-creased from 100 mA to 200 mA. The small beam and intense heat loads provided by the upgraded APS requires unique and innovative approaches to beam position monitoring. To meet the need for a reliable diagnostic system for the APS upgrade, the next generation X-ray Beam Position Monitoring System (XBPM) is required which includes the first XBPM (XBPM1), the Intensity Monitor (IM1) and the second XBPM (XBPM2). This paper presents progress and status of the current configu-ration of the XBPM system especially the development work involving the IM1 and XBPM2. The R&D work to develop an alternative XBPM1 using the Compton scattering principle is also presented.

TUPH34	The Use of AM Technologies for HV and UHV Components and Vessels	114
	A. Stallwood, D.J. Butler, G.M.A. Duller DLS, Oxfordshire, United Kingdom
	AM technology (3D Printing) in plastics and metals has now been in commercial use for over 30 years. However, the application of this technology in vacuum environments has been limited, due to the material porosity and additives used in the manufacturing techniques. This paper reports on the testing and use of FDM (Fused Deposition Modelling) PEEK and DMLS (Direct Metal Laser Sintering) metal components inside a UHV environment. Specifically covering the use of DMLS to successfully produce a complex vacuum vessel operating at 10^-6 mbar, as used on the new VMXm beamline at Diamond Light Source. Vacuum testing the vessel has demonstrated that this manufacturing technique has the potential to produce vessels that are capable of holding 10-10mbar.

TUPH36	Metal 3D Additive Machining for in-Vacuum Beam Instrumentation	121
	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.

TUPH39	The Design of LCLS-II Photon Beam Containment System	133
	H. Wang, Y. Feng, S. Forcat Oller, J. Krzywiński, E. Ortiz, M. Rowen SLAC, Menlo Park, California, USA
	LCLS-II will produce very powerful photon beams. Unlike conventional synchrotrons, the LCLS-II beam containment components withstand not only the high average beam power and power density, but also the instantaneous thermal shocks from pulsed FEL beam, which can reach ~9mJ/pulse. With beam repetition rate up to 1MHz, regular metal based beam collimators and absorbers will no longer work, because of the likelihood of fatigue failure. And because of the poor thermal conductivity, the old LCLS B4C based absorber would need very shallow glancing angle and take valuable beamline space. Hence, a low-Z and high thermal conductivity CVD diamond based photon beam collimator and absorber systems have been developed in LCSL-II. The initial damage tests using LCLS FEL beam provided positive results that graphite coated CVD diamond can endure per pulse dose level to ~0.5eV/atom. For the beamline and personnel safety, in addition to the passive CVD diamond collimators and absorbers, newly developed photon diode beam mis-steer detection systems and conventional SLAC pressurized burnt-through monitors have been also introduced in the photon beamline system design.

WEOPMA03	Application of Additive Manufacturing in the Development of a Sample Holder for a Fixed Target Vector Scanning Diffractometer at SwissFEL	158
	X. Wang, P. Hirschi, J. Hora, H. Jöhri, B. Pedrini, C. Pradervand PSI, Villigen PSI, Switzerland
	Whilst the benefit of additive manufacturing (AM) in rapid prototyping becomes more and more established, the direct application of 3D printed part is still demanding. Exploitation of AM opens the door for complex and optimized parts which are otherwise impossible to fabricate. In the meanwhile, specific knowledge and aspects in analysis and design process are still to be explored. For a fixed target vector scanning diffractometer [1] at SwissFEL we developed, manufactured and tested a 3D-printed sample holder with carbon fiber reinforced plastics material. The diffractometer for serial crystallography is dedicated to collect diffraction patterns at up to 100 Hz on many small crystals (< 5 µm) by scanning the sample support in a continuous, arbitrary motion. The high dynamics arising from curved trajectories in the xy-plane requires a light and stiff sample holder which attaches the sample to the stage. In addition to 3D printed parts, an aluminum counterpart produced by CNC machining has also been tested and carefully evaluated. Our work in the course of development process on topology optimization, design, manufacturing and dynamic verification tests will be presented. [1] C.

WEOPMA04	Mechanical Design of a New Precision Alignment Apparatus for Compact X-ray Compound Refractive Lens Manipulator	168

	Funding: Work supported by the U.S. Department of Energy, Office of Science, under Contract No. DE-AC02-06CH11357. A prototype of compact x-ray compound refractive lens (CRL) manipulator system has been developed at the Argonne National Laboratory for dark-field imaging of multi-scale structures. This novel full-field imaging modality uses Bragg peaks to reconstruct 3D distribution of mesoscopic and microscopic structures that govern the behavior of functional materials, in particular, thermodynamic phase transitions in magnetic systems. At the heart of this microscopy technique is a CRL-based x-ray objective lens* with an easily adjustable focal length to isolate any region of interest, typically in the energy range of 5-100 keV or higher, with high precision positional and angular reproducibility. Since the x-ray CRL manipulator system for this technique will be implemented on a high-resolution diffractometer detector arm that rotates during diffraction studies, compactness and system stability, along with the ability to change focal length (zooming), became key design requirements for this new CRL manipulator system. The mechanical design of the compact x-ray CRL manipulator system, as well as finite element analyses for its precision alignment apparatus are described in this paper. * http://www.rxoptics.de/intro.html
