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
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 – M 15 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
Project Challenges • Instrumentation for Low Current data – BPMs and BCMs – Mitigation • BPM – M 15 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 k. G, requiring 465 A – Mitigation – reflecting requirements against selected PSs, identifying potential alternates
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
Project Challenges • Installation at the same time as 12 Ge. V 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!
