  • Mike - update songsheet w/ names

• Detector table/shielding
  • Waiting on table top, then rails/posts assembly
  • Drawings for lead hut assembly

• Detector status
  • Detector Triax (4) and SHV (2) => cables pulled and hanging near dump
  • DAQ status
  • Assemble BGO/PMT and detector chassis

• Magnet
  • Magnet QA, measurement/model benchmarking, readiness for installation
  • Magnet PS cables => pulled to power load on wall
  • Rack/magnet ground cable => bounded to braid near dump

• Current monitoring
  • Faraday cups current monitor => Ganged with FCUP
  • A5 current monitor => 7mm aperture, requires I&C controls (Windham next week)
  • A6 current monitor => Radiator

• Beam Position/Size diagnostics upstream of Dump
  • Harp installed upstream of dump
  • BPM installed upstream of dump
  • Beam line viewer => Matt repaired, requires camera alignment
  • X-ray viewer => Joe relocated to look at detector hut, requires X-ray card

• SImulations
