Revision as of 13:26, 9 January 2015
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
Contents
[hide]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
- 4 channels of +12V, 0.21 amps per channel
- 4 channels of -12V, 0.21 amps per channel
- 1 channel of +200V, the leakage current on the silicon strip detecter is 3.3 micro-amps
