Found both VFDs with OF3 fault (over voltage during constant speed operation).

Thursday, January 08, 2015, 16:37: Cycled power on the chiller to clear faults.

TM#4 from south hot cell to the conditioning station no target is attached to the module.

TM#4  with no target has been moved from conditioning station to the south hot cell.

I connected TM4 and CS vacuum system after TM4 move. CS roughing pump was started first this morning. Later, Anders, Bill and I started 3 turbo pumps on TM4 and CS. The pumping down is good so far. The CS vacuum system ion gauges are turned on also.

Electrical check of TM#4 with Ta#45 at the conditioning station, see attached pdf for details.

The helium pressure test on TM4 HS line at conditioning station is done. No leak. I also leak checked all vacuum seals on TM4 service cap. They are all good.

TM4 has been connected at CS which includes high current cables, water lines, EE cable, and Enizel lens cable. The HV cover has been  installed onto the TM4 service cap.The CS water system is started. All water signals are good so far.   Anders will start  HV and heaters conditioning on next Monday.

The TH will be locked during the TM1 conditioning time due to  an interference issue between CS HV cover and a gas analysis valve on top of TM1. A work permit has been issued for the conditioning job because of it.

I did an electrical check on TM1 at CS. The resistance check:A-B 3.918m ohm, A-C 5.905m ohm,A-D 4.070m ohm,B-C5.462m ohm,B-D3.633m ohm. They are very close to the check we did in SHC. The only unusual thing I found during the check is the ohmmeter reading between A and 60 KV common (6.2K )and the Megga reading between them  at 250 V which is 0. I repeated 4 times and always got the same readings. However, after so many times check, the Megga reading between A and 60KV   suddenly went back to normal(300 M at 250V) at the final check.  And,it stays at 300M now.  All other measurements are same as we did at SHC before.         

There is a huge leak on TM1 containment box window. I did a 70 psi helium pressure test on all TM1 water circuits this morning. The LD base leak rate was 0.0XE-9 atm.cc/sec. When applying the 70 psi helium to containment box window circuit, the leak rate on LD jumped to 1XE-4 atm.cc/sec in 5 seconds.I released the helium source right away,t but the conditioning station is full of helium  molecules already, and the leak rate on LD stays at 1xE-5 atm.cc /sec.  The leak on this circuit is huge.    Other water lines are good.        

Changed by Dave Morris. 

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

TM1 has been partially disconnected at CS for tomorrow move. The CS TP1S is still running and will be stopped and disconnected tomorrow morning.

Dan and I vented CS and TM1 with Argon gas before it is moved this morning.

Caled cyclotron ops to open P23 and confirmed penthouse valve open.

Filled up TK2 to 21 in water leve.

 The communications chip has been replaced. The electronics box has been grounded (see attached pdf).
