  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

  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 14, 2011 • Installation completion – start of Physics • November 14, 2011

  5. Project Status • Regions 1 and 2 designs complete and material ordered • Region 3 design well underway • New FZ vacuum chambers on order – Due this month • Finalizing FZ magnet stand designs • Addition of Harps on Articulating Arm and upside down girder • M15 style BPMs rather than stripline • Calorimeter controller repaired and SW upgrades underway • Worked through issues on BPM and BCM • Requires 12 BPM “Transport” modules • Awaiting testing to validate design decisions

  6. Project Challenges • Instrumentation for Low Current data • BPMs and BCMs • Mitigation • BPM – M15 style, new electronics, test to verify this will achieve needed results • BCM – use existing hardware, test to verify this will achieve needed results (planned for mid Feb.) • FZ Magnet PS requirements evolving • Need up to 8 kG, requiring465A • Mitigation – reflecting requirements against selected PSs, identifying potential alternates

  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 – SW resource already assigned

  8. Project Challenges • Installation at the same time as 12 GeV upgrades during 6 month down • Mitigation – alerted groups which will be in high demand – schedule planning in process • Slow Raster issues raised at last collaboration meeting – waveform generators and “hole” in raster pattern • Mitigation – Physics Electronics group addressing, update meeting Tuesday • Maintain strong communication – highlight issues early!
