Hall Task List Spring17¶

"Stands" unless indicated otherwise. "???" means the task definition wasn't clear to the last Ops/Commissioning meeting

Hall¶

Change over water solenoids for the SS diode absorber trays. Water tank fitted – to connect. Need to connect drain - stands
~~Nikhef Hall probes Melissa/Ajit - still have 2 failed – complete~~
Tracker vacuum. Ed - in progress
~~Tracker turbo pumps. Craig - stands~~
Luminosity monitor sensor 3 Craig/Ed - stands
Luminosity monitor sensor 1 Craig/Ed - stands
Diffuser iris 4 - re-test with field ~~on 7/2/17.~~ Stands
~~‘Splash guard’ for Tracker compressor plumbing in trench. Stands~~ superseded
~~Tracker compressor change-over/testing.~~

~~Ramp commands to SSU M coils – remedial action taken.~~
Alarm handler/state machine. Moved to static config – expected complete end week ~~13th~~ 24th March. miceecserv reboot on Thursday 6th.
~~Water pump GUI password protected, #1891~~
Network errors messages – in progress
- Need to specifiy a port number for all CArepeaters - thus need to reboot all IOC-type machines. Need to find good time for miceecserv reboot.
- Possibly related to the Watchdog failure, which hasn't re-appeared.

Spectrometer solenoids

Commissioning of Change over water solenoids for the SS diode absorber trays- T. Hartnett – complete, new tank installed, plumbing to be completed prior to re-test.

Focus Coil

FC Data logger GUI to be tested and verified – ongoing:
- have access to the QPS data itself; have a plug-in to get this Labview data into Excel, but need to understand the channel mapping
- Need a Windows PC running Labview client (rdesktop in) - can put on one of the Hall Probe machines
PT100’s on FC in R9 to be fitted – ongoing 0 sensors will be glued leave till summer?
FC power supply failure – repair with Sorensen

Hydrogen System

~~Cryo-cooler for LH2 system moved from Vacuum control station 9 rack to H2 control room information to the control system is not available in new location, request to resolve. P. Hanlet to prove.~~ Will be restricted to LH2 Control System
~~Hydrogen level sensing commissioning – P. Warburton to advise~~ is on the dedicated LH2 workplan

Check off power distribution records – J. Webb, A. Gallagher ???
Records of testing to be made available - A. Gallagher ???
Update all Mice drawings and issue to Mice Wiki page in PDF format – J. Webb, I. Mullacrane to advise ???

MICE Hall

24V supply for draw wire strain gauge required. Installation complete, commissioning and testing to be completed in hall. – A. Gallagher, J. Webb
Magnet Interlock alarm is inoperative investigation required – DL engineer ???

Spectrometer solenoid Backup Helium Valve: Relay required to repeat valve state to the control system as status of valve is only known local to the valve. - I. Mullacrane
Cable/Software check needed to prove which magnet Cold-heads are connected to which Cryo-compressors and that GUI has the correct compressor RS232 communications associated with the correct Cold-heads. - I. Mullacrane, J. Webb
Review of FC cable numbers. - J. Webb Link Box labelling has been cleaned up
Fit plinth to EMR rack. – A. Gallagher
Temperature instrumentation upgrade for Decay Solenoid – I. Mullacrane
RR2 to be updated in HevaComp – DL engineer
Main 5th AC unit adjacent to mice substation reinstated, drawings require mods to show location and feeder details - J. Webb
