  1. g2p/GEp Beamline Status Tim Michalski Project Lead

  2. Overview Facilitate the design, procurement, and build of the beamline – up to the target chamber Experimental Plan Project Overview Project Status Project Challenges with risk mitigation

  3. Experimental Plan Target Elevated by ??? *** - FZ1 and FZ2 in position for 2.2 GeV run, but with half field strength on FZs and Target magnets

  4. Project Overview • Design, procurement, component calibration and testing • Now through May, 2011 • Some components arrive after May • Access to Hall A for installation • May 16, 2011 • Installation completion – start of Physics • November 19, 2011

  5. Project Status • Regions 1 and 2 designs complete and material ordered • Region 3 design complete – final review and procurement in coming weeks • Calorimeter controller repaired and SW upgrades nearly complete • I&C electronics designed and being built • Addition of SR PS chamber, w/ cooling • Resource planning integrated into 6MSD schedule • Several changes to the run plan being evaluated

  6. Project Challenges • Instrumentation for Low Current data • BPMs and BCMs • Mitigation • BPM – short M15 style, new electronics, tested • BCM – new receiver • FZ Magnet PS requirements evolving • Need up to 4 kG, requiring 231A for FZ1 • Need up to 8 kG, requiring 465A for FZ2 • Mitigation – assessed capabilities of magnet power supplies in Hall C – meet requirements – assembling spares

  7. Project Challenges • Acquisition of equipment from various sources • FZ magnets, corrector magnets, slow raster, new BPMs, power supplies, controllers • Mitigation – get control as soon as possible, test and calibrate early (before installation) • Resurrection of Tungsten Calorimeter • Reposition in beamline, re-establish functionality, recalibrate • Mitigation – Controller extracted from Hall A, repaired, new PC104 SW nearly complete

  8. Project Challenges • Slow Raster issues raised at last collaboration meeting – waveform generators and “hole” in raster pattern • Mitigation – New function generator – Testing in Progress • Installation at the same time as 12 GeV upgrades during 6 month down • Mitigation – tied to detailed 6MSD planning – all resources identified in schedules – have ~3 weeks float

  9. Project Challenges • Proposed changes to run definition – a) target height when upstream, b) 1.157 GeV run when target at pivot • Mitigation – Run new orbits on optics, address changes in FZ2 magnet position and articulating arm – defined impact to work and calendar time • Maintain strong communication – highlight issues early!
