April 4, 2011 Commissioning Needs-Soler 2

Commissioning Needs•MICE shift 23/3/11

—Shift went well and most systems tested (see P. Hodgson’s report last week)

—However, BPM was not able to be tested

•Beam Position Monitor:—Contacted Pierrick Hanlet and Alan Bross to see what could

have been the problem—Discovered that HV was badly configured after EPICS tests —There are two CAEN SY127 crates (one on top of large

SY527 crate and one next to BPM) oThese need to be “daisy chained” but were notoSY127 cable connected to SY527 cable (which is at CAEN for repair)

oWith instructions from Pierrick, connected one SY127 to the other and terminated connections properly (however need to test)

Commissioning Needs•Henry removed MICE DAQ PCs from rack DAQ-04

—It includes: Grid data mover PC, "micestore", all miceacq* servers and DAQ KVM system.

—PCs are currently in R76—Old rack to be removed and new rack to be installed—Goal is to reinstall PCs around 14 April—Consequences:

o No data taking until reinstalled o KVM box has been removed - machines that connect through it will need to use a local keyboard and monitor (miceraid1&2; micecss1; micepps1; targetctl1).

o No backups of eLog, MICEmine, etc. (micestore removed)o Cannot test BPM again until system reinstalled
