MOM Summary 19/01/10 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. 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 Chiller controller outside of the MLCR has been fixed to prevent it crashing on a daily basis

MOM Summary 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. Cryo Compressers 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 Daresbury Guys came down on the 12 th 13 th Jan. Helped to install Luminosity Monitors in target Synch. Brought replacement component for target PSU Installed new 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 18 th 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 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 26 th to 31 st of Jan to fix CAMAC. I have requested documentation so that a non-daq expert can plug leads back in.

MOM Summary 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 15 th. 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 Running No running planned for January because of shutdown. Machine Physics to run from 2 nd to 14 th 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 28 th 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 Shift 1: Friday 5th February 16: :00 Shift 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 Dean Shift 3: Mon 8th February 16: :00 Shift 4 & 5: Wed 10th February. This is for the 16h activation run at 2V beamloss. 09:00 - Finish There may be the possibility of additional shifts after the 10th but this is TBC.

MOM Summary 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 Beamloss vs rate studies

MOM Summary 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)
