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

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.

 The targets UC#22,23,24 have been repackaged into the newer stronger pails, and have been placed back in the mini vault with new numbers. See attached PDF for details.

 Sic#39, Ta#59, C#2, UC# 32 & 30 have been moved from the spent target vault to the mini vault. See the attached pdf for details of the vaults.

 Targets UC#38,40 Ta#62,63 SiC#44 have been moved from the spent target vault to the mini vault in preparation for F-308 loading. See attached PDFs for details.

SiC#30,ZrC#7,Ta#44,TiC#4, and Ta#41 have been moved from the spent target storage to the mini storage. See attached PDF for details of the orders of the pails in the mini vault.

All targets in the mini storage (4) have been moved from there and placed into the F-308s and those have been moved to the mech services room.

Five targets have been moved from the spent target storage to the mini storage. The targets that were moved are UCx #'s 6,7,8 , SiC #28, and Nb #6.

 Targets Ta#50 and SiC#34 have been transferred from their old pails to new ones. Ta#50 was done on April 12th 2019 it was moved from pail #148 to pail #200 and a new field measurement was done and found to be 3.57mSv/hr. SiC#34 was done on April 18th 2019 it was moved from pail #143 to pail # 206 and a new field measurement was done and found to be 2.20mSv/hr. Both measurements were done by the RAM that is mounted at the south hot cell.

April 24 2019

Target Ta#46 has now been transferred to a new pail with a number 207 from pail 143 it was 3.62 mSv/hr when removed from the south hot cell.

April 25 2019

Target Ta#47 has now been transferred to a new pail with a number 201 from pail 137 it was 2.25mSv/hr when removed from the south hot cell. The bag that the target was in has shown signs of degradation.

Target Ta#45 has now been transferred to a new pail with a number 202 from pail 124 it was 1.45mSv/hr when removed from the south hot cell. The bag that the target was in was destroyed. Also in the pail was a shutter, IMG Gauge, some altem parts, wire and bolts.

The extraction electrode from Ta#47 was added to this pail as it was left behind from last transfer.

The SiC#29 CTL target has been taken apart with the help of Isaac and Chad. Electrical measurements were done between Target and Heat Shield as the target was disassembled. Work was done on October 2nd, 4th, 7th and 8th.

The megger showed about 30kOhm at 50V with the following changes

• Bolts for CTL block loosened
• Above bolts removed
• CTL block pulled away from Heat Shield
• CTL block removed
• Heat Shield lid removed
• Bolts for target removed
• Shims between target and insulators

The megger showed about 50kOhm at 100V with the following changes

• Target removed. Measured between cathode restraint and HS.

The megger showed OL at 540V with No 3 insulator removed. A measurement on No 3 insulator while it was sitting on the HS showed 70kOhm at 120V confirming that the insulator can no longer hold voltage.

While taking off the coil retainer plate, Chad noticed that all bolts were not tight.

Looks like the UC target s #1 and #2 were found invalidprize winners for their all inclusive trip to Chalk River and have thus been placed back in to storage for the next draw. In their place a pair of lucky Ta targets won, seems to be Ta lucky draw this year, Ta#28 and #29 have been placed in the mini storage for several fabulous day and wondrous nights, before being whisked away on their all inclusive one way trip to Chalk River. See attachments for the status of both vaults.

Two shielding blocks  above vacuum station at TH west end were opened for inspection. Checked ITH:MP1, MP2 lubricant color and level through sight gauge on pumps. They are still ok.  Restored the shielding blocks.  Checked ITM:MP1 by decay tank (Mirror checked  sight gauge by north wall). Added lubricant to ITM:MP1 to middle level on sight gauge.  

 On October 22 2024 the spent SIC#44 returned from CNL was repacked in a new pail it was in pail 275 and repacked into pail 298 it was 2.34mSv/hr when removed from the south hot cell.

It was placed in the very back of the mini vault.
