TUPH15	Friction Stir Welding Attempts for UHV Applications: Stainless Steel/Aluminum	interface, site, factory	57
	A. Ermakov, C. Martens, U. Naujoks DESY, Hamburg, Germany
	At DESY in Hamburg an investigation was started to join aluminum chambers with stainless steel flanges by friction stir welding. First results will be presented. It will be shown that there is only a small effect of hardening in the contact zone at the stainless-steel side, a small amount of particles are given and the diffusion zone is about 3 microns, but with a very irregular effect on the structured junction. Because of that, the influence of the surface and the welding parameters on the process will be investigated in the future.

TUPH34	The Use of AM Technologies for HV and UHV Components and Vessels	vacuum, detector, operation, cavity	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.

TUPH38	Preliminary Design of the Magnets of HALS	quadrupole, dipole, sextupole, multipole	129
	B. Zhang, Z.L. Ren, X.Q. Wang, Y. Wang, H. Xu USTC/NSRL, Hefei, Anhui, People's Republic of China
	The Hefei Advanced Light Source (HALS) is a future soft X-ray diffraction-limited storage ring at National Synchrotron Radiation Laboratory (NSRL) of China. This project aims to improve the brilliance and coherence of the X-ray beams and to decrease the horizontal emittance. The lattice of the HALS ring relies on magnets with demanding specifications, including combined function dipole-quadrupoles (DQs) with high gradients, dipoles with longitudinal gradients (DLs), high gradient quadrupoles and sextupoles. All these magnets have been designed using POSSION and Radia. Preliminary design of them are presented in this paper.

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
