I connected TM2 to TCS and started water system.

Plant Services group (Tony) will contact a service tech on Monday.

Water system will be switched off over the weekend.

Thursday, July 14, 2016, 13:24: Claus from Daikin is on site to troubleshoot.

The VFD driven fan motor has failed. Temporarily blocked air-flow through failed fan to improve air-flow to radiator. A new motor will be ordered (Curtis).

Thursday, July 14, 2016, 15:39: Stopped cooling system for the day

Friday, July 15, 2016, 08:16: Cooling system started

Friday, July 15, 2016, 15:00; Cooling system stopped.

Last Friday July-15, TM3 was leak checked at TCS. All air to vacuum seals on service cap are good.  Helium pressure test on  TM3 water lines(except GE, HS, and Window) were done. Leak detector has no response at 0.0xE-9 atm.cc/sec. They are leak free.

Friday July 15: did HV tests (with no target installed and with the anode wire removed ). <br>

TM3 went up to 22.5kV. At this voltage it started sparking. The EL was kept at 1/2 with respect to the HV BIAS. <br>

Also HV tests were done while the EL was kept at zero V. In this case, the EL voltage was once in a while spiking  up (up to 4kV). <br>

During sparking we saw responses in the vacuum. Checked the Service Cap (with the HV Cover) in the Target Hall: we couldn't hear/see sparks there.  <br>

The HV was turned off in the same day, after 5:30pm.

I started vacuum system.

I started TCS water system. The chiller does not work properly still. But, It will not affect the TM3 HV conditioning.  HV cover is installed on TM3 in TH. The module is ready for HV conditioning.

Helium pressure test on TM4 HS line at TCS  is done.Leak detector 0.0X E-9atm.cc/sec.  5minutes, 70psi helium.    No response on LD.

I started TCS water system and installed HV cover onto TM4.  The TM4 containment box is supplied with water also. TM4 is ready for conditioning at TCS.

Update schedule weekly. See attachments 1,2

I stopped TCS water pumps this morning . The argon venting for TCS is in processing.

 The locations (ports) for the RGA and CG1S was swapped today by Anders and Isaac to provide clearance for the North Hot Cell ventilation. Attached photos show old and new locations.

TM#3 has been moved from the north east silo to the conditioning station.
