	Funding: Work supported by Brookhaven Science Associates under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy A new type of electron-ion beam overlap monitor has been developed for the RHIC electron lenses. Low energy electrons acquire high energies in small impact parameter Coulomb scattering collisions with relativistic ions. Such electrons can traverse thin vacuum windows and be conveniently detected in air. Counting rates are maximized to optimize beam overlap. Operational experience with the electron backscattering detectors during the 2015 p-p RHIC run will be presented. Other possible real-time non-invasive beam-diagnostic applications of high energy Coulomb-scattered electrons will be briefly discussed. Most of this material appears in an article by the same authors entitled "High energy Coulomb-scattered electrons for relativistic particle beam diagnostics", Phys. Rev. Accel.

MOPOB10	Design of the HGVPU Undulator Vacuum Chamber for LCLS-II	ion, vacuum, undulator, operation	89
	J.E. Lerch, J.A. Carter, P.K. Den Hartog, G.E. Wiemerslage ANL, Argonne, Illinois, USA
	A vacuum chamber has been designed and prototyped for the new Horizontal Gap Vertically Polarization Undulator (HGVPU) as part of the LCLS-II upgrade project. Numerous functional requirements for the HGVPU assembly constrained the vacuum chamber design. These constraints included spatial restrictions to achieve small magnet gaps, narrow temperature and alignment specifications, and minimization of wall erosion and pressure drop within the cooling channels. This led to the design of a 3.5-meter length, thin walled, extruded aluminium chamber with interior water cooling. FEA stress analysis was performed to ensure the chamber will not fail under vacuum and water pressure. A cooling scheme was optimized to ensure water flow is sufficient to maintain temperature without the risk of erosion and to minimize pres-sure drop across the chamber.

TUPOB66	Procedure for the Alignment of the Beam in the Electrical Axes of the Pi-Test RFQ	ion, rfq, solenoid, emittance	639
	J.-P. Carneiro, L.R. Prost, J. Steimel Fermilab, Batavia, Illinois, USA
	The PI-Test Radio-Frequency Quadrupole (RFQ) has been in operation with beam at Fermilab since March 2016. The RFQ accelerates H⁻ beam from 30 keV to 2.1 MeV currently with 20 mus pulses and a maximum current of 10 mA. Once fully conditioned, the RFQ is expected to enable CW operation. Simulations with the beam dynamics code TRACK predict that a misalignment of the beam at the RFQ entrance can possibly deteriorate the transverse and longitudinal emittance at the RFQ exit without necessarily impacting the beam transmission. This paper discusses the procedure developed at Fermilab to align the beam in the electrical axes of the RFQ. Experimental results are shown together with predictions from TRACK.

The High Luminosity upgrade of the LHC at CERN will use large aperture (150 mm) quadrupole magnets to focus the beams at the interaction points. The high field in the coils requires Nb3Sn superconductor technology, which has been brought to maturity by the LHC Accelerator Research Program (LARP) over the last 10 years. The key design targets for the new IR quadrupoles were established in 2012, and fabrication of model magnets started in 2014. This paper discusses the results from the first single short coil test and from the first short quadrupole model test. Remaining challenges and plans to address them are also presented and discussed.

Extensive prototyping of storage ring magnets is ongoing at the Advanced Photon Source (APS) in support of the APS Multi-Bend Achromat upgrade (APS-U) project. As part of the R&D activities 4 quadrupole magnets with slightly different geometries and pole tip materials, and one sextupole magnet with vanadium permendur pole tips were designed, built and tested. Magnets were measured individually using a rotating coil and a Hall probe for detailed mapping of the magnetic field. Magnets were then assembled and aligned relative to each other on a steel support plate and concrete plinth using precision machined surfaces to gain experience with the alignment method chosen for the APS-U storage ring magnets. The required alignment of magnets on a common support structure is 30 micron rms. Measurements of magnetic field quality, strength and magnet alignment after subjecting the magnets and assemblies to different tests will be presented.

Mechanical tolerance stackup analyses using Teamcenter Variation Analysis are carried out to determine the part and assembly level fabrication tolerances. Finite element analyses using OPERA are conducted to estimate the effect of fabrication and assembly errors on the magnetic field of a quadrupole magnet and to determine the allowable tolerances to achieve the desired magnetic performance. Finally, results of measurements in R&D quadrupole prototypes are compared with the analysis results.

	To achieve the luminosity goals in a next generation linear collider, acceleration and preservation of ultra-low emittance particle beams is mission critical and requires a precise alignment between the main accelerator components. PACMAN is an innovative doctoral training program, hosted by CERN, with the goal of developing high accuracy metrology and alignment methods and tools to integrate those components in a standalone, automatic test bench. The method will be validated on CLIC components, a proposed Compact Linear Collider currently studied at CERN. The alignment between the electrical center of the Beam Position Monitor (BPM) and the magnetic center of the associated Main Beam Quadrupole (MBQ) is of particular importance to minimize the emittance blow-up, and therefore in the focus of the PACMAN project. The two components have been independently characterized on separated test benches by stretched and vibrating wire techniques. Preliminary conclusions are presented in this paper, with emphasis on the characterization of the electrical center of the BPM.
