This page contains a list of to do items for installing the triplet polarimeter for the Spring 2015 GlueX run. Items that used to be on this page are now at the bottom in Items From Before January 2015

Expected Timeline

  • February 2 - 5 (?): Kei visits ASU
  • mid-February: ship triplet to JLab
  • First week after delivery: Survey by JLab
  • February 16 - March 27: installation
  • March 28 - April 2: testing
  • April 3 - May 4: physics beam

Hardware Division

  • ASU
    • motor (data sheet)
    • controller
    • power supply
      1. 4 channels of +12V, 0.21 amps per channel
      2. 4 channels of -12V, 0.21 amps per channel
      3. 1 channel of +200V, the leakage current on the silicon strip detecter is 3.3 micro-amps
    • 32 short SSI cables with Lemo
    • vacuum rated limit switches (data sheet)
  • JLab
    • fADCs
      1. 2 fADC250s on PSC VXS crate
    • 32 coax cables with Lemos on both ends (Fernando). Require 55ft to racks
    • turbo vacuum pump (Tim)

Things to do at ASU

  • packaging, shipping
  • testing(?)

Things to do at JLab

  • preparation of hardware before shipment
  • installation
  • testing with source(?)

Management/Safety

Analysis Procedures
