The TiC#5 post irradiation inspection was done on Wed. June 14 and Mon. June 19. This target didn't have any obvious issues but it didn't produce much beam. The inspection revealed that the container was quite embrittled and showed significant damage, though it was not broken. The FEBIAD grid looked fine, despite the large anode current draw (indicating that current was flowing elsewhere). The gas line looked fine though the gas injection to this target looked as if it wasn't connected. But there was a plug on the unused line, so it must have been correct. No other obvious signs that would explain the poor performance. Pictures are can be found here https://documents.triumf.ca/docushare/dsweb/View/Collection-37913

TiC#4 has been installed onto TM3

TiC#3 sucessfully installed and ready for leak and electrical check.

In preparation for F-308 loading, three pails were moved from the main storage vault to the mini storage vault. The following pails were moved:

• Pail 270 (C#3)
• Pail 276 (UC#39)
• Pail 231 (UC#41)

Target Index spreadsheet updated, attached.

The old thermocouple wire has been sucessfully removed from the module.

Thanks Bevan, Travis and David.

The bad thermal motor protection relay for the crane has been replaced with a new unit. Crane was tested in pendant(local) operation and all drives worked.

to reduce the radioactive shining from  SHC Ta# 40 target.

The yellow steel plug is put on SHC in TH. The spent target is inside the SHC.The field around the SHC area in TH is so high that we have put it on. It will be moved out on this Thursday just before the spent target move. 

ThO#1 has been removed from TM1 and placed into the plastic dissection box.

Containment box cover has been reinstalled as per usual.

ThO#1 has been installed onto TM1 and is ready for leak and electrical checking. High current fasteners torqued to 130 in lbs.

The target hall has been locked-out as per Document-70039.

Forced IG1, IG1S and IG2 to switch on BIAS power supply

Wednesday, July 12, 2017, 11:53: 70 kV at 0.16 mA

2 sparks observed shortly after 70 kV was reached

Wednesday, July 12, 2017, 12:59: No sparks for the last hour.

BIAS power supply off. Forces removed.

 I have tested all of the compressors for TCS. All are operational and cycled as they should. 

Shorted TGHT with new high current connector assembly and heated to 600 A. Temperature measured on half way point on cable ~ 70 deg C and on connector ~60 deg C at 600 A, 45 / 40 deg C at 400 A. Target Hall locked out during test

Friday, November 06, 2015, 14:35: Roughing

Turbos was started around 4pm. Later it was found that the manual valve for the two turbo pumps on the service cap was closed. The valve was open and pumping resumed. The roughing vacuum was high and increased into Saturday morning. The vacuum system was switched off on Saturday.

Purged MP1 using the purging function. Performance recovered. Started rouging.

Monday, November 09, 2015, 09:18: Started TP1S

Monday, November 09, 2015, 09:22: Started TP1 and TP2

Monday, November 09, 2015, 09:33: All 3 turbos at speed

Leak found on F/T for multipin connector

Tuesday, November 10, 2015, 09:53: stopped turbos

Tuesday, November 10, 2015, 16:53: Roughing

Tuesday, November 10, 2015, 18:24: TP1S started

Tuesday, November 10, 2015, 18:30: TP1 and TP2 started

Tuesday, November 10, 2015, 18:41: All 3 turbos at speed.

Thursday, November 12, 2015, 08:30: Purged backing pump using purging function. Vacuum in backing line recovered to previous value. 

Module connected for HV testing. No target heating possible. All F/Ts tied together to HV common. EZL connected.

Friday, November 13, 2015, 11:20: Started water package

Friday, November 13, 2015, 11:52: 1kV on BIAS and 1 kV on EL

Friday, November 13, 2015, 12:54: BIAS/EL 10 / 5 kV

Friday, November 13, 2015, 12:59: BIAS/EL 15 / 7.5 kV

Friday, November 13, 2015, 13:04: BIAS/EL 20 / 10 kV

Friday, November 13, 2015, 13:08 : BIAS/EL 22 / 11 kV. Some sparks.

Friday, November 13, 2015, 13:17: Sparking at 22.5 kV. Had to return to 20 kV to recover. Back at 22.5

Friday, November 13, 2015, 13:21 : BIAS/EL 24 / 12 kV. 

 Friday, November 13, 2015, 13:27: Heavy spakring around 24.5 kV. Had to return to 20 kV to recover.

Friday, November 13, 2015, 13:31: Attempted to increase voltage again. Sparking started around 23 kV. Had to lower to 20 kV.

Friday, November 13, 2015, 13:36: 9 sparks for the last 5 min.

Friday, November 13, 2015, 13:45: Spark rate reduced, but multiple sparks encountered again at 20.5 kV. Reduced back to 20 kV

Friday, November 13, 2015, 13:50: Increased sparking at 20 kV. Had to lower to 18 kV

Friday, November 13, 2015, 14:07: Back at 20 kV

Friday, November 13, 2015, 14:13: BIAS and EL off

Monday, November 16, 2015, 08:18: Fault on chiller. Reset chiller unit on the roof.

 The BIAS voltage was brought up to 70 kV today and held there for 1h. No sparking observed.

Tested all 3 compressors and MP2

Chad and Anders inspected the test target in the hot cell today. The lid had been previously removed.

• The EE looked to have performed well. 
• A piece of Ta foil was found inside the heat shield. It is not clear if this has been there during operation or if it entered the heat shield while in the hot cell. The foil has markings which indicate that it has seen heat.
• Travis measured 40 MOhm at 500V between heat shield and anode after the target was removed.

 TM1 has received the Ta#37-LP and has been pumping since thursday. This morning the pressure gauges read, IMG1: 1.6x10^-6 T and IG1: 7.4x10^-7 T.

The high voltage power supply has been connected to all high voltage feedthroughs and the voltage raise to 42 kV. 

High voltage conditioning started around 20 kV and after few minutes we were able to go up to 40 kV. 

The pressure increases on both locations, IG1 went up to 8.1x10^-7T and IMG1 went up to 1.8x10^-6T.

The module is good to go. 

In preparation for shipping of the spent targets five have been moved to the mini storage. The following target were moved to the mini storage, SiC#26, Ta#36, UC#9,10,11.
