TM#4 with SiC#37 has been moved from the conditioning station to the east target station. A measurement was taken on TM#4 as it was being removed from the conditioning station, the location was on the side of the service tray access panel approx one metre away and the cover fully exposed, the reading was 750uSV/hr.

On maintenance day Tuesday, the roughing of the target station could not go below 1.5 Torr. A brief troubleshooting on Tuesday was unsuccessful in determining the cause. Leak checking continued on Wednesday by David and Anders. A leak was finally found on the multi pin connector feedthrough due to the seal between the connector and flange on top of the nylon insulator. Upon re-tightening the connector, the leak could be stopped and the module pumped down to allow starting of turbo pumps.

TM disconnected by David and Yasmine Feb 8th

 TM#4 with SiC#37 has been moved from the East Target Station to the South Hot cell.

 Electrical check of TM#4 with SiC#37 attached post beam. A short was found between the Einzel Lens and Chassis. See attached PDF for details.

 SiC#37 has been moved from the South Hot Cell to the Spent Target Vault. It was placed in Pail #165 and put in spot 3B of the vault and it measured 25.8mSv/hr upon removal from the hot cell. See the attached PDF for details

This afternoon Ta#51 was removed from TM2 and SiC#36 installed.

All new fasteners used. High current fasteners torqued to 130 in lbs.

TM#2 with SiC#36 has been moved from the conditioning station to the west target station.

The electrical check of TM#2 with SiC#36 attached. Post beam at the south hot cell. See attached results allow the before beam electrical check results are posted here as well.

 The spent SiC#36 has been moved from the south hot cell to the spent target vault.

by David and Chad after target removed from module:

Anode to target @500V - 65Kohm
Anode to HS - dead short
Target to HS@500V -62Kohm.

Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.

Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module in hot cell) febiad coil left twisted a bit when torqued up.

Results of the electrical check of TM#2 with no target after the repair and with the SiC#35 mounted on the module.

TM#2 with the old SiC #35 has been moved from ITW to the south hot cell.

Electrical check of TM#2 with the SiC#35  post beam run. See attached PDF for details.

On November 24th 2016 the spent SiC#35 was moved from the south hot cell to the spent target vault. see attached pdf for details.

 Targets SiC#34 , Ta#45,46,47,50 have been moved from the spent target vault to the mini vault.

The bundle of electrical checks, first one is the Iglis that failed, the second is the everything passed at the hot cell and the third is a the conditioning station under vacuum.

Conditioning by ISAC operations

Saturday, September 24, 2016, 11:15: RGA on for heater conditioning. (kept off during HV conditioning)

Sunday, September 25, 2016, 07:44: TGHT and TBHT voltage jumps during heater ramping. Likely contact between target and heat shield. Contacted ISAC operations and asked to abort ramping at current values. TGHT/TBHT 500 /270 A

Monday, September 26, 2016, 08:22: ISAC operations resuming ramping to 550 A. Corrected TGHT voltage at ISAC TS was ~6.2 V at 580 A. Expected voltage at TCS would then be 6.2 + (3.4+2.9)E-3*580 = 9.9 V. Limit set at 9.5 V.

Monday, September 26, 2016, 09:09: Increased TGHT voltage limit to 9.6 V to allow it to reach 550 A.

Monday, September 26, 2016, 10:17: Voltage limit increased to 10.2 V which allowed the current to go to 575 A

Tuesday, September 27, 2016, 08:08: Conditioning complete. Ran at 575 / 270 A and 47 kV for about 1 hour. Conditioned cold to 49 kV.

TM#4 with SiC #34 has been moved to the east target station.
