The spent Ta#59 was moved from the south hot cell to the spent target vault. See the attached for details.

TM2 was moved from the Conditioning Station to ITE, with SiC#38 target.

Helium pressure leak check on TM2 HS line at TCS is done. No leak. Also, Helium are sprayed to gas line adapter and fittings. No leak. TM2 is connected at TCS. Anode plug on TCS is connected to module 52pin connector. Water system is started. Vacuum pumping down is good. HV cover will be installed today.

Thursday, November 07, 2019, 10:35: Tested source to 30 A on TGHT, TBHT and COIL. ANODE at 100 V.

Tuesday, November 12, 2019

The FEBIAD source worked well over the weekend. The anode current limit was adjusted twice to stop voltage limiting. About 5E-8 A on the FC with TGHT=580A, TBHT=300A, ANODE=200V,150 mA, COIL=50A. Bias was conditioned to 30 kV

 Results of the electrical check of TM#2 with the old Ta#59 target and target free.

Ta#59 has been removed from TM2 and it is now ready for electrical check.

 TM#2 with Ta#59 has been moved from the ITE to the south hot cell.

Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine.  The positional check on gas line between TM2 and ITW will be fulfilled next Tuesday during module disconnection. 

Yesterday a leak was discovered in the ISAC-I experimental hall. The leak appears to be at the connection between the evaporator and the return water line. 1 in of water was lost from TCS:TK1. The water is currently valved off to prevent further leakage.

A fault reportt has been submitted to mechanical services - awaiting response.

Leak repaired by Mechanical Services. A brass fitting had cracked and was replaced with a galvanized fitting.

The SMP main control panel and remote control module were updated in order to implement the following items which were deemed desirable during commissioning:
 

•     24 VDC line added to E-stop circuit:
  
  Previously the E-stop relay cut power to only 120 VAC. This means that the lid rotation motor would stop instantly, but since the lid open/close valve is powered by 24 VDC which comes from a power supply unit, there would be a short delay while the unit powers off in which the valve was still active. This could result in a situation in which, for example, someone is operating the pendant to close the lid and another person recognizes a hazard and presses the E-stop on the main panel, but the lid does not stop closing for approximately 3 seconds while the operator is still holding the "close" button down.
  
  To rectify this issue, the 24 VDC line was routed through a NO contact of the same E-stop relay that controls the entire 120 VAC supply to the system. This was tested on Oct. 25, 2019 - working.
  
   
• Status feedback signals to remote control room:
  
  Previously status signals for "Lid raised", "Lid Centred", "CW Limit", and "CCW Limit" were only displayed as light indicators on the main control panel. It was determined during remote operation that it would be helpful to have these signals sent back to the software interface so that an operator does not need to use a camera to look at the light indicators.
  
  
  Electrical drawings and cable schedule have been updated to reflect these changes. The SMP will be tested again using the commissioning plan checklist to confirm no there were no inadvertent effects on the rest of the same from these changes.

The attenuation of the SMP shielding was measured as part of SMP commissioning (Document-170404, R1, Section 4, Test #8)

The field on the shutter side of TM3 was measured without any shielding as it was removed from a storage silo.  At 0.5m from the edge of the module the maximum field was 5.00mSv.  After installation into the SMP the maximum field outside the SMP shielding at 0.5m from the edge of the module was found to be 27uSv/hr. The resulting attenuation is 185x

Expected attenuation was calculated by Joe Mildenberger assuming that the majority of the activated components in that module are either copper or aluminum.  With 6" of steel shielding (SMP shield vessel plus vacuum vessel), the attenuation factors were found for the following isotopes: 

Na-22 (created in Al): 115

Co-60 (created in steel (Fe) or Cu): 70

Mn-54: (created in steel (Fe) or Cu): 200

 UC#28 has been moved from the south hot cell to spent target storage. The target was placed in pail number 219 and placed in spot 1C of the vault, it was 12.6mSv/hr upon removal from the south hot cell. Also the spent target vault is now full and can not currently accept anymore targets.

TM3 was moved into SMP Oct 25 morning.  After two nights pumping down, SMP CG1 read 30mtorr this morning.  The pump is stopped. SMP will be vented soon for TM3 moving back to silo. 

 TM#4 with UC29 has been moved from the south hot cell to the west target station.

UCx#28 has been removed from TM4. Guard screws on 5(10) pin connector had to be removed to get the connector to un-seat properly for removal.

TM4 was disconnected in ITW.  See checklist.

A braided grounding strap was attached to the aluminum gear box support on the SMP shield box structure, and grounded by attaching it to the exterior of an electrical conduit located in the south-west corner of the B2 area at the top of the silo in that corner.  The braiding was also connected to the stainless steel support structure for the SMP vacuum pump.

TM4 with UC# 28 target has been moved from ITW to the South Hot Cell. Shield plug installed in ITW.

 The targets in the mini storage have been loaded into the F-308.
