Checks of the wiring for the IMG are complete and have passed.

Hi Remote Handling,

The guage on the IMC circuit in the Target Hall is reading atmosphere, and the bellows is currently relaxed (i.e. expanded), whereas it should be reading about -20inHg and the bellows should be contracted (i.e. compressed).

I've attached a photo of what the guage and fittings should look like when pumped down to -30inHg.

Either the IMC circuit has been vented, disturbed, or it has some kind of leak.  When I was in the Target Hall this morning, I saw the gauge bent around the railing at an awkward angle with a pretty severe bend in the copper line, it appeared to have been disturbed by the temporary glove box sitting at that level used by Rob Walker for nuclear ventilation work.

I will co-ordinate pump-down and leak check of the circuit, but the Conditioning Station cannot be used until this is repaired.

Cheers,

Grant

IG1S elbow o ring seal and a blank off cap o-ring seal beside the elbow were replaced on ITE entrance module top last Friday. IG1s has a higher than normal reading so i leak checked entrance module top last Thursday and found leaks to 5x E-8 atm.cc/sec leak on one of (or both of )these two o-rings seals. they are too close to identify exactly on which one was leaking so both o rings were replaced.  other air to vacuum seal on entrance module are leak free. 

Changed by Dave Morris. 

New value is 1E-5 T (old value was 7.09E-5 T)

HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine.  Water level and system resistivity will be monitored for a while.

LALCW P5 and P6 are switched on  for cooling HALCW.  HALCW MP2 is in operation now.

Disconnected  TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test.

  I switched off TCS and TM2 vacuum pumps. The TM2 will be disconnected at TCS today and moved to silo on next Monday.

The TM4 is still under vacuum at TCS. It will be vented tomorrow morning.

I disconnected TM4 vacuum system at TCS.

The ITE and TM4 have been vented with Argon . TM4 vacuum system is disconnected in ITE.

I stopped turbo pumps and disconnected vacuum system on TM2 and CS. The TM2 will be moved to SHC for C seal installation on "D" water block.

I replaced flow wheel and coil on ITW MSP water flow sensor which is located in ITW pit. Before replacement, I checked the signal strength and frequency form e-board on this circuit. The signal was good in 10minutes watching. Still, I replaced them. The flow sensor works fine after replacement. I made a comment  on Isac e-fault system about this issue.

They were moved for TM3 inspection job last week. All the bolts on the panel are hand tight only now since they will be removed out for camera installation during next stage inspection.

I moved 5 shielding blocks from ITW to block storage area.

I moved 5 shielding blocks from ITW  to block storage area for preparing the TM1 disconnection. Air sampled and swiped blocks and ITW and everything is fine.Fiona was with me all the time during the moving.

  All water interlock checks for ITE had been done. The ITE water signals strength and frequency(Espcially on MSP circuit) had been checked from electrical room, and everything is good.

5 shielding blocks have  been transferred from  ITW to ITE. ITE ventilation is opened, and ITW closed. All ITE water  signals have been checked for frequency and strength.They are all good. ITE is ready for taking proton beam.

I moved5shielding blocks from ITE to block storage area, This is a job for preparing ITE vacuum surge investigation and leak check.

Water interlock check  on ITW is done. All water signals are strong on EL panel.  ITW is configured to take proton beam.

I moved 5 shielding blocks from ITW to ITE. The ITW  is configured to take proton beam.

5 shielding blocks have been moved from ITE to ITW. ITW is configured to take proton beam now.
