Water Now the ice has cleared I am able to get on the roof again. Could do with getting the conductivity readings fed back similarly. I believe A.Nichols has approached J. Governs wrt this – I haven’t heard anything yet.

  1. Water • Now the ice has cleared I am able to get on the roof again. • Could do with getting the conductivity readings fed back similarly. I believe A.Nichols has approached J. Governs wrtthis – I haven’t heard anything yet. • The water level appears to keep dropping – I’m assuming that it is being topped up by J.Governs. No evidence of any leaks though? • Magnet Chillercontroller outside of the MLCR has been fixed to prevent it crashing on a daily basis MOM Summary 19/01/10

  2. MICE HALL • Decay Solenoid • The New collar was fitted last week, Transfer line vacuum appears to have improved as a result. • Scaffold was put up for Linde last week. • Servicing due this week. • It will be necessary to start cooldown immediately to ensure DS is ready for machine physics. • CryoCompressers • Unsure of status of these. • Other Work • Willie’s team are continuing to drill holes in the steelwork in preparation for the tracker solenoids. MOM Summary

  3. Daresbury • Guys came down on the 12th 13th Jan. • Helped to installLuminosity Monitors in target Synch. • Brought replacementcomponent for target PSU • Installednew interlock for target frame (will not be functional yet though) – but there is an issue with a return signal to be solved. • There is still some issue with TC cabling numbers to the target to be resolved. • (Fixed) an issue with the beam-on light on the upper DS Gate (I think it is now permanently off!) • IM returned on Mon 18th • Look at return signal on target interlock. • Wiring of power to TOF 2. • Take a closer look at TC cabling to the target. • Anything ELSE? MOM Summary

  4. Luminosity Monitors • Paul Soler came down Tue to Fri last week to install LM • Cabling pulled through by Daresbury guys • Electronics is in the bottom third of rack next to target. • One PMT has failed, Paul may be able to get a replacement for machine physics but it doesn’t compromise operation. My understanding is that it may just increase the S/N ratio slightly. • DAQ • As far as I am aware there is no change - He plans to come 26th to 31st of Jan to fix CAMAC. I have requested documentation so that a non-daq expert can plug leads back in. MOM Summary

  5. Lab 7 • Helium leak developed in Lab 7, source not yet found. This emptied the cylinder • Due to planned power cut in R1, Lab 7 was effectively switched off on Friday 15th. I believe the plan is to get everything working again in preparation for the trackers moving to the MICE hall. • Power Cut • The power was cut in the MICE hall on Saturday morning (This was a planned cut to allow the power to be switched to a new distribution board) • Unfortunately this also affected the MLCR (not forseen) and several computers were affected • The DS vacuums had been previously isolated but without the computers the vacuum pumps on the turret could not be restrarted until Monday. MOM Summary

  6. Running • No running planned for January because of shutdown. • Machine Physics to run from 2nd to 14th February. • We have informally requested 5 shifts, formal confirmation and shift dates tbc • I have NO plan for User run. What would we like to achieve during this period? • Rehersal • There will be a rehersal on the afternoon of the 28th of Jan to ensure that all equipment appears to be functional. Simultaneously Beam Line training will be given to beam line experts • This will be preceded by a meeting in the morning (10:30) to determine the ‘Beam Line Expert’ rota MOM Summary

  7. Shift 1:   Friday 5th February 16:30 - 00:00Shift 2: Sat 6th Feb OR Sun 7th Feb. This has yet TBC by Dean.  This could be a 16h shift if we can utilise the time. If we can, then we have got a shift for free! Thanks DeanShift 3: Mon 8th February 16:30 - 00:00Shift 4 & 5: Wed 10th February. This is for the 16h activation run at 2V beamloss.  09:00 - FinishThere may be the possibility of additional shifts after the 10th but this is TBC. MOM Summary

  8. NOTE : All TBC! • Shift 1: Objectives: • Re-establish DAQ and target operations • Reset and setup all Detectors (GVA1 / TOF1 & 2/ KL) • Re-establish Online Reconstruction • Commission Luminosity Monitors (Parasitic) • Shift 2 & 3 • Commission Luminosity Monitors • Calibrate FNAL1 monitor and GVA1 monitor • Adams Beamlossvs rate studies MOM Summary

  9. Shift 4 & 5 (16h Combined) • Establish Target Operation at Required Beamloss of 2V • Ensure all Detectors are Running • Run for 16 Hours • If target insertion rate is 1 every 2.56 seconds then the total number of actuations in 16h is 22,500. Therefore there will need to be at least 4 calibration runs! (One every 3.5 hours) MOM Summary
