1. g2p/gep Beamline Project Overview Tim Michalski Project Lead

2. Outline Facilitate the design, procurement, and build of the beamline – up to the target chamber Project Plan Capture Requirements / Design Challenges Project Challenges with risk mitigation

3. Experimental Plan Low Current Runs – 50-120 nanoamps Tuning Runs – 30 microamps (straight through only)

4. Project Plan Design activity planned several months ago Recently started design activities Design, procurement, component calibration and testing –Now through May, 2011 Access to Hall A for installation –May 14, 2011 Installation completion – start of Physics –November 14, 2011

5. Requirements/Design Challenges Addition of chicane –2 FZ magnets and articulating arm New Beam Position Monitors –for low current beam position measurement –high accuracy Re-use of Tungsten Calorimeter –for calibration of current monitor –high accuracy Rastered beam – Ø25mm at target Safely deliver beam to target – PSS/MPS

6. 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 – Assigned resource from Accelerator Ops

7. Project Challenges Beam Position Monitor is new technology design and electronics for low current –Mitigation – prototype device is in test now – verify performance to g2p/gep needs – track procurement, assembly, bench test 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 Maintain strong communication – highlight issues early!
