Phase 2 (intermediate) and Phase 3 (Final) polishing is complete on all water blocks on TM2 (minus ground electrode circuit which has only had a cursory cleaning). Phase 2 with 2000 grit wet sand paper and isopropynol for 1 minute with tool at 75 psi, Phase 3 with Veltex polishing cloth for 1 minute with tool at 75 psi.

The source tray side of the water block jig has been removed in preparation for moving the module to the  conditioning station for electrical tests.

The back half of the water block jig (services tray side) has been sucessfully located onto the module.

About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle wiggling to get them to seat.

the warm cell mock-up has been inserted into the warm cell and final preparation for the remote test are being made.

I visually inspected HALCW system including water station section, both target pits, and de-ionizer system.  No small leak and drip was found .  The inspection in both target pits will be repeated after flow sensors are replaced.

A rotary limit switch was installed, attached to the shaft adjacent to the drive motor for the vertical drive system. This limit switch is not yet wired to the control system and operational - this will be done at a future date and the e-log will be updated.

 TM1 started venting at 4:15 pm with Argon. I will leave the valve open over night.

 Lead gasket IRH1633 was installed today according to assembly drawing IRH1618 Rev B.

 The conditioning station has been vented with argon. Time taken is not known but it is less than 3 hours. See attached picture for convectron gauge readings. CG1A is in air.

Yesterday, TM4 B line was supplied with water at TCS for testing.  TCS: IG1 and IG2 had big response on it. See attachment. The water was disconnected right away, and line was purged. Vacuum recovered after overnight pump.

 It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.

 EPICS conversion updated and corrected by Mike Rowe.

The corelation betwenn the local value on the gauge controllers and the read back valiues in EPICS was compared. Data can be found in a previous  e-log

 The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down.

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

Water system will be switched off over the weekend.

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.

Bevan attempted to start pumping down on TM4 today remotely but there was an issue.  He will report on Monday.

I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:

- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise)

- Closed the VAT valve between the scroll pump and the nuclear ventilation
