TUPH15	Friction Stir Welding Attempts for UHV Applications: Stainless Steel/Aluminum	interface, HOM, site	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.

TUPH23	Field Quality From Tolerance Analyses in Two-Half Sextuple Magnet	sextupole, alignment, multipole, lattice	78
	J. Liu, R.J. Dejus, A.T. Donnelly, C.L. Doose, A.K. Jain, M.S. Jaski ANL, Argonne, Illinois, USA
	Funding: Work supported by the U.S. Department of Energy, Office of Science, under Contract No. DE-AC02-06CH11357 Sextupole magnets are used extensively in particle ac-celerators, synchrotrons, and storage rings. Good magnet-ic field quality is needed in these magnets, which requires machining the magnet parts to high precision and is the primary driver of the high fabrication costs. To minimize the fabrication costs, a magnetic field quality study from tolerance analyses was conducted. In this paper, finite element analysis (FEA) using OPERA was performed to identify key geometric factors that affect the magnetic field quality and identify the allowable range for these factors. Next, geometric and dimensional tolerance stack-up analyses are carried out using Teamcenter Variation Analysis to optimize the allocation of the geometric tol-erances to parts and assemblies. Finally, the analysis re-sults are compared to magnetic measurements of a R&D sextupole magnet.

TUPH28	Calculation of Orbit Distortions for the APS Upgrade Due to Girder Resonances	ground-motion, resonance, dipole, quadrupole	95
	J. Nudell, Z. Liu, C.A. Preissner, V. Sajaev ANL, Argonne, Illinois, USA
	Maintaining sub-micron-scale beam stability for the APS-U Multibend Achromat Lattice places strict requirements on the magnet support system. Historically, magnet vibration requirements have been based on physics simulations which make broad generalizations and assumptions regarding the magnet motion. Magnet support systems have been notoriously difficult to analyze with FEA techniques and as a consequence, these analyses have been underutilized in predicting accelerator performance. The APS has developed a procedure for accurate modeling of magnet support systems. The girder mode shapes are extracted from these analyses and exported to accelerator simulation code elegant to calculate the static beam amplification factor for each mode shape. These amplification factors, along with knowledge of damping coefficients and the character of the tunnel floor motion, may then be used to predict the effect of girder resonances on beam stability and validate the magnet support designs.

WEOPMA05	Application of Industry Recognised Development Tools and Methodologies, such as Six Sigma to Facilitate the Efficient Delivery of Innovative and Robust Engineering Solutions at Synchrotron Facilities	synchrotron, hardware, experiment, controls	184
	S. A. Macdonell DLS, Oxfordshire, United Kingdom
	Synchrotron facilities play a key part in the delivery of world leading science to facilitate research and development across multiple fields. The enabling technology designed by engineers at these facilities is crucial to their success. The highly academic nature of Synchrotron facilities does not always lead to working in the same way as a commercial engineering company. However, are the engineering requirements at Synchrotrons different to commercial companies? Exploring the parallels between research and commercial companies, can we show that the tools and methodologies employed could benefit engineering development at Synchrotrons? This paper provides a theoretical discussion on the commonality between engineering developments at Synchrotron facilities compared to commercial companies. How methodologies such as Design for Six Sigma and in particular tools such as stakeholder analysis, functional tree analysis, FMEA and DoE could be utilised in the design process at Synchrotrons. It also seeks to demonstrate how implementation could aid the development of innovative, robust and efficient design of engineering solutions to meet the ever-increasing demands of our facilities.

THPH05	An Improved Polarisation Analyser for the I16 Beamline at Diamond	detector, vacuum, polarization, scattering	346
	M.H. Burt, S.P. Collins, S. Green, I. Horswell, J. Li, G. Nisbet, R. Pocock, J. Spiers, K.G. Wilkinson DLS, Oxfordshire, United Kingdom
	The project to upgrade the I16 polarisation analyser was necessary to increase its functionality and to introduce a more robust construction. The requirement that the analyser was to be mounted on a diffractometer meant the construction needed to be as lightweight and as compact as possible. This provided opportunities to explore new collaborative ways of working with both in-house and external suppliers. The paper describes the approach taken to develop lightweight aluminium vacuum chambers working with a company specialising in additive layer manufacturing. In addition, the design of lightweight and compact slit assemblies are detailed; these were developed in collaboration with a supplier of driven linear stages. A novel requirement for the analyser is to have a detector mounted on a rotation axis in vacuum. The results of working with the in-house detector group to develop a design to with all the necessary thermal and electrical connections are described. The paper also describes further use of additive layer manufacturing to produce prototypes that allows the design of a cable management system to be optimised where previously using 3d CAD models had proved unsatisfactory.
