Diffuser

• IOC is running
• State machine is near completion, needs testing
• Run control using the state machine needs to be tested
• Hardware all okay

TOF

• HV can't be run on remote
• HV test on Ckov
• PMTs all okay

Tracker

• Cryo - 3+4 are cold (D/S), only these will get wave guide on
• Cryo - probably cold by Friday
• Waveguides need to be in; waiting on John Govans to bring them over on forklift
• Cabling of D/S tracker this afternoon
• Ground the cryostats
• Short to be fixed on cryo 3

• CAEN VME controller needs to be switched to D/S rack, currently they are in the U/S rack
  • D/S ones are in Sheffield
  • Or use SVS; SVS is regarded as a fallback
  • Round of initialisations and simple standalone readout tomorrow
  • Use current Adey C+M to drive DAQ
  • Merge tracker code in with DATE
  • Attempt to readout, using old trigger
  • Attempt to bring in new trigger, need to get to that in next two days
  • Yordan will test Overton FPGA code
  • Use LED system once Alan and Paul arrive on Friday

• Tracker Controls
  • Merging James's non-expert code; Ed and Pierrick, following TOF HV
  • Hardware things; CAEN controller, moving back to SVS is possible but not tested, CAEN controller is not tested; Pierrick casts doubt on possibility
  • Need to run a new fibre next few days, 3 fibres spare
  • Daresbury needs to finish readout of MKS (vacuum) and temp controllers
  • Need interlock CANBus fixed

• Unpacking
  • No change

• OnMon
  • Adey has spoken with Rhys, he will be here later this week to discuss

• OnRec
  • Dobbs and Adey requested status separately from Melissa, no reply
  • No change
  • Rogers to chase

• Run plan
  • Need to introduce appropriate delays on LED before it hits the trigger
  • LED needs to pulse first

KL

• No known problems; it is on SYV527

EMR

• Two front end boards noisy need replacing
• Missing power supply for LED

Ckov

• No known issues

LM

• Pierrick, when he was installing the IOC trace, he noticed the LM power supply came disconnected; need to check that it has not been damaged
• Check voltages on PMTs
• Look for dark currents off the PMT

DAQ

• No known problems
• New machines
• New DATE
• New linux install
• General tests, but all looked okay
• Need to test with real data

Controls

• EMR control and monitoring of rack is likely to slip

Control room

• Failed disk on miceserv
• micethin network broken
• niggles
• NAGIOS deployment
• Network switch okay
• Reset of a mice thin may break network connection

Datamover

• Need to update movefiles script; change to Step IV
• Not expecting automated data mover to run
• Janusz will be around on 21st January

PPS

• Nothing new
• Note that beam stop will be closed for PPS reasons while the target is operating

Beamline

• Target - S1.9 is now installed, few niggles
  • Will do testing on fibres
  • Swap controller with R78 controller
  • Check quadrature
  • Run up target before Friday lunchtime
  • Need to check with ISIS that there is vacuum
• Decay solenoid
  • Attempting to fix DS trip on low current this week
  • Currently DS is at 200 A; after today it will be owned by expert
  • Should be in the hall, may be tripping off fridge, need to have easy access to MLCR/Linde fridge PC
• NC magnets
  • Water from ISIS is marginal, may cause problem
  • Fenced and signs still up in synch, Henry to take signs down later today following tests
• Beamstop serviced and working
  • Need to be closed for D1 and D2 and target frame lowered
• Proton absorber
  • No known issues

OnRec

• Go through with Adam after lunch on Wednesday 14.30 onwards
• No request for SOC
• Action on onrec to move onrec02 and 03 into the server
