1. MICO Meeting, 1 st March 2010 Terry Hart (MOM) - Decay Solenoid - Targets - DAQ - March User Runs Plans - Suggestions

2. Decay Solenoid (DS) Cooldown started on Feb. 26 and going well so far Cooldown expected to be done on March 8 25 Feb, 20102

3. Target 2 Target 2 in R78 – Stopped after small, but noticable deviations from nominal position noticed (next 2 slides) – Dismantled and to be examined for Direction w.r.t. stator of wear for each bearing Systematic off-axis force due to coil quality or misalignment – Achieved over 2,160,000 actuations – Non-metallic dust evident Though to be from anti-rotation flat Next shaft to have flat surface polished Harder bearing material to be tried Dust appears to be well-contained – David Findlay invited to view as-stripped components 25 Feb, 20103

4. 4 Target 3 – Parts being made now, but might need to incorporate rotary table later – Enough parts ready for 2 more identical targets – Field mapping of stator to start next week – Results of analysis of Target 2 will determine construction plan schedule

5. 25 Feb, 2010 Feb. 10 T2 Acceleration and Position Left: acceleration vs. time Right: position vs. Time – ‘BCD’ is Beam Center Distance 5

6. Feb. 21 T2 Acceleration and Position Left: acceleration vs. time Right: position vs. Time – About 0.4 mm drop over 11 days 25 Feb, 20106

7. DAQ Electronics documentation being written DAQ cabling simplified before Machine Physics – New detector calibrations needed and done Software configuration of software repository done Will finish OS and DATE upgrades of DAQ PC – DATE: DAQ software framework Time permitting, make DATE status available on EPICS – EPICS = Experiment Physics and Industrial Control System 25 Feb, 20107

8. User Run Plans for March March 1 – Short run to check that everything runs well with new personnel and updates to DAQ and online monitoring – Alain suggests doing short runs like this once per week Once Decay Solenoid is on – Check and complete (emittance, momentum) matrix – Measure particle production vs. beam loss for different particle species – Proton absorber studies – This will be worked out my Marco (the new MOM), ISIS, and MICE 25 Feb, 20108

9. Suggestions (1 of 2) Specify list of plots to check and how often to check – First order check: Make sure detectors are on and at correct voltage – Higher order check: Make sure distributions are o.k. – Online monitoring plots are being worked on For calibration runs, suggest that detector experts submit form to MOM specifying – Purpose of calibration – Necessary particle rate for channels of interest that shift crew can check with online monitoring Scheduled weekly short run – Make sure everything still works with ongoing development – Make sure new procedures are correct and followed – Alain’s idea Follow up on BPM rate discrepancy between Large X plane and Large Y plane – Voltages checked o.k. – Anything else to check? 25 Feb, 20109

10. 10 Suggestions (2 of 2) Follow up on new measurement of integrated beam loss which doesn’t seem to work below around 200 mV –Adam Dobbs working on this List possible ISIS timing modes and work out MICE target settings for each mode – I talked to Dean Adams about that, and he said that was already worked out with Paul Kyberd. Develop list of magnet currents for particle type and purpose of run –For instance, I found out from Linda that for calibration runs, Q7-Q8-Q9 currents are reduced to spread out beam to hit outer TOF detectors –This could prevent overreliance of ‘magic spreadsheet’ in micewinvis in MLCR Make sure ordered magnet power supply water flow meters and software installed.
