Five spent targets have been moved from the Spent Target Vault to Mini Storage in preparation for transfer to F-308s in February. The following targets were moved Ta#35, Ta#39, SiC#27, UC#12, ThO#1

Move went well no problems readings at East Target Station were very high at 500mSv/hr.

Ta#35, in pail #88, has been place into spent target storage, in spot 6C. Upon removal from the South Hot Cell it was 411mSv/hr our hottest target to be placed into storage to date. There are 8 free slots for targets left in the vault.

On April 08th, all water lines in TM1 had been helium pressure tested(70psi) at conditioning station. No leak had been found.

TM2 has been moved from the Conditioning Station to ITE with Ta#59 target.

Tm2 with Ta 59 has eben connected in ITE. Turbo pumps are started. See checklist

See attachment

TM2 was moved from ITE to South Hot Cell. Tantalum 58 target.

 An electrical check made at NHC right after TM4 moving from ITE.

the TM4 with new target Ta #63 installed in SHC and an electric check was made by David. 

 electric check done in ITE. 

 David made an electric check after TM4 been moved to NHC from ITE. The target is still on the module. Please find out attached pic for detail.

 David did electrical check after target removed from TM4 at NHC. see attachment pls.

Upon attempting to lower Pail 211 into their tile hole, CNL encountered issues with the pail getting stuck. They shipped the pail back to TRIUMF and requested we perform an investigation. The investigation report is attached.

The pail contents must be re-packaged into a new pail.

Note: the F-308 is currently sitting in the Meson Hall warm cell at approximately 250 uSv/h at 0.5 m.

Dose for primary worker (Chad Fisher) who inspected the cable, unbolted the flask lid, and handled the pail briefly: approx. 104 uSv

Dose for secondary worker (Danka Krsmanovic) who swiped the pail and flask to check for contamination: approx. 70 uSv

Tried to leak check TM4 Ta57# at TCS. LD failed to pump down properly at fine range. It always tripped at 4 torr. I cheeked all vacuum lines seals and adapters on top of module to LD. Everything is good. Chad said the VCRs at SHC can not be tightened any more. Discussed with Anders, we decide to move module TCS and helium pressure test there.  The same difficult happened last time on TM4 UCx24# at SHC when leak check. But,it is solved by pressurize the line at SHC last time.  

The HS line was pressurized with 70 psi helium on Oct 04th at TCS.. LD 0,00X E-9atm.cc/sec no change in 2 minutes. No leak.

Ta #47 has been removed from TM4.

One containment box cover bolt would not come out. Upon attempted removal with the stud remover the bolt sheared...which is not uncommon...just hasn't happened in many years...CBB being stuck or shearing.

Nine pin connector shows the typical "arcing" mark.

 TM4 with Ta#42 was HV conditioned to 35kV with the optics tray at 17.5kV. There was some vacuum response while ramping but well within normal. Attached is a screen shot and the associated data.

 The turbo pumps have been turned on and are running

The pumps have been turned on at ~9:30 this morning. Current values are 6.61 Mohm TCS:DIC1 @19.4 C. HV testing will start momentarily.

 The HV conditioning reached a maximum of 44kV today before a spark took out the canbus card. I will attach the data once I have had a chance to format it.
