Ta#56 has been moved from the south hot cell to the storage vault. It was placed in pail#169 and place in slot 2C of the vault. Also the vault is now full with 24 spent targets and can no longer accept any new targets. See the attached PDF for further details.

 Ta#56 in pail #169 was repacked and placed into #269 and was placed in the mini vault at the back. It was 3.86mSv/hr upon removal from the NHC. See attached files for details.

The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak.  It was helium pressurized at TCS this morning. Leak rat:2.5 XE-7 atm.c/sec. The result  is same as last time check. No concern.

TCS vacuum system and water system have been started as well. Everything looks fine.

Thursday, November 09, 2017, 10:40: BIAS / EL to 30 / 15 kV. 400 uA on BIAS

Bias was stable for 1 hour. Handed over to RIB ops for heater conditioning.

 TM#2 with Ta#55 has been moved from the conditioning station to the west target station. The field was measured on the access panel to the service chase and the field was found to be 430uSv/hr at one meter from the module.

TM2 has been connected in ITW. All turbo-pumps are started. Everything works fine.

TM disconnected by David and Yasmine Feb 8th. One of the water couplings were leaking for a short while when disconnected. NCR 10836 submitted by Max

 TM#2 with Ta#55 has been moved from the west target station to the south hot cell.

 Ta#55 has been moved from the south hot cell to the spent target vault. It was 30.4mSv/hr upon removal from the hotcell, placed in pail #161 and put in spot 7A of the vault.

 The results of the various electrical check done on the target module on November 7th and 8th of 2017. Checks were done with the old Ta#54 target without a target and finally with the new Ta#55 target. See the attached PDF for results.

Electrical check of TM#2 with Ta#54 at the south hot cell. See attached PDF for details.

Containment box has been replaced onto TM2, interior of containment box vacuumed, and Ta#54 installed with new fasteners (high current torqued to 130 in lbs).

 TM#2 with Ta#54 has been moved from the south hot cell to the conditioning station.

Cooling water not yet connected to TM.

High leakage current still observed. 200 uA at 22 kV. Did not go past 25 kV. 

Friday, September 29, 2017, 14:05: Started heater ramping to 580 / 200 A at 1 A/min

Friday, September 29, 2017, 14:09: BIAS / EZL / EE at 20 / 10 / 1.5 kV. BIAS current at 90 uA

Monday, October 02, 2017, 10:29: Accidentally set BIAS current limit to 0 A (step size too large) at 28 kV. This also caused the TGHT to got to 0 A. Recovered to 580 A in 10 - 15 s.

Monday, October 02, 2017, 12:07: Ramping down heaters at 2 A / min

 TM#2 with Ta#54 has been moved from the conditioning station to the west target station.

 TM#2 with Ta#54 has been moved from the west target station to the south hot cell.

 The spent Ta#54 target has been moved from the south hot cell to the spent target vault. It was placed in Pail #157 and put in spot #5B of the vault.

TM#2 with Ta#53 has been moved from the conditioning station to the west target station.
