Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the  blue F/T insulator for the multi-pin connector (see attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced but still significant. The o-ring will likely need to be replaced. Tuesday, November 10, 2015, 17:00: Could not find new o-ring. Cleaned groove and o-ring and applied o-ring grease. Re-attached F/T.

Tuesday

Steerer wire had disconnected again. See DocuShare for photos.

Thursday, November 12, 2015

Leak checked the fixed F/T and the panel for steeerers. No leaks found.

Target to Anode and target to Common showed ~ 500 kOhm values. No leaks above 3E-9 atm-cc/s seen. See attached.  

Update TH schedule according to changes. See attachment 1,2 .

update TH schedule weekly. See attachments 3,4

 Problem found between ANODE (F) and chassis 90 kOhm. See attachment for details.

ISAC operators attempted HV conditioning over the weekend.

I stopped the TM3 and TCS vacuum pumps and water system. The TM3 is disconnected and vented. It will be moved to silo this afternoon.

TM#3 has been moved back to the NW silo.

TM#4 with UC#14 was moved from the south hot cell to the conditioning station.  Here are the results of the electrical check of the module with the UC#14 target while at the hot cell.

Thursday, November 26, 2015, 09:55: PS energized. EE connected to power supply.

Thursday, November 26, 2015, 11:41: Applied some current and voltage to all power supplies. All looks good.

Some sparking around 5 kV. Turned out to be a bad cable connection. Fixed with David W.

Thursday, November 26, 2015, 15:04: BIAS/EL/EE 20 / 15 1.5 kV

Thursday, November 26, 2015, 15:43: Handed TCS over to ISAC operations

 Target heated over the weekend. EE went into current limiting (down to ~100 V) a while after the target was at temperature.

Monday, November 30, 2015

Target conditioned by ISAC operators to 30 kV without any problems.

EE current limit increased to about 26 mA in an attempt to recover. Cooling down target to investigate.

TM4 vacuum has been connected in TCS. All vacuum pumps were started yesterday. The pumping down of TM4 and TCS are good so far.

I did helium pressure test on TM4 HS line at TCS this morning.  70psi helium 3 minutes, 0.0xE-9 atm.cc/sec base leak rate. No response. No leak.

TM4 has been connected at TCS. The water system is started. The TCS HV cover for TM4 is installed also. Basically, The TM4 is ready for conditioning.

Weekly update TH schedule according to changes. see attachment 1,2 .

Update TH schedule before the weekend. see attachment 3,4

I turned off TCS vacuum and water pumps. The TSC and TM4 are still under vacuum condition.

 After conditioning over the weekend the EE developed a short. This was confirmed by measuring the resistance between EE and Heat Shield on the module yesterday.

 It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.
