A steel plate  is covered on TCS. TCS roughing pump  is started now. The TCS will be pumping down during mini-shut down.

Weekly update TH schedule for beam schedule 131. See attachments 1,2

The ITE is configured to take proton beam.

TM2 was disconnected at ITW. 3 water circuits in ITW gave been looped to keep 75 GPM water flow to ITW. HS line was purged at HS. RPG got the water sample.

Argon venting is started

Broken cable has been replaced however a cable has hopped some pulleys inside. After two hours in cell the job was stopped with cables still off pulleys. Alternate tooling will have to be made and the job will continue Monday.

Maico entered the hot cell and re-strung the skipped cable back onto the pulleys this morning. Manipulator is now operational.

conductor insulators itd0053 and 54 have been replaced on TM2. All fasteners (1/4-20 x 1 1/4 vented) torqued to 60 in lbs.

Chad and I did the leak check on TM2 heat shield line. LD base leak rate:0.0xE-9atm.cc/sec. Base pressure:0.0X E-9 torr. The line is leak free.

All turbo pumps are started. Two gas valves for Febiad run are opened. Pumping down is good so far.

Update TH schedule after job delay on TM2 Febiad target. Everything should be back to schedule on last two targets. See attachments.

TM4 was disconnected at ITE this morning. It was moved to SHC  after. No alpha alarm issue has been happened during and after move. The ventilation pumping down procedure on ITE was fulfilled during the move.

TM4 was disconnected at ITE this morning. It was moved to SHC  after. No alpha alarm issue has been happened during and after move. The ventilation pumping down procedure on ITE was fulfilled during the move.

Chad and I did a leak check on TM4 HS line with new Ta target installed. Base leak rate 0.0xE-9 atm.cc/sec. base pressure 0.0XE-4.   splayed 2 helium to each VCR joints and did 10 seconds helium flush. No response on LD during the test. The HS line is leak free so far. It will be helium pressurized at TCS later.

All turbo-pumps are started. The pumping down is good so far.

70 psi helium ,2minutes to  TM4 HS line. LD base leak rate 0.0xE-9 atm.cc/sec. No leak.

The system works fine. All water signals to TM4 at TCS are normal. HV cover is installed on to TM4 at TCS.

TCS is vented. TM4 is disconnected and TCS.

David Wang and I accessed the NHC today to check if the proposed duct routing (IRH1618) will interfere with servicing or replacement of the TCS turbo pump.  A piece of plywood was placed in the future position of the NHC/TCS partition wall (IRH1609), and a ducting elbow was placed at the approximate position of the nearest elbow to the turbo pump.

David concluded that the ducting in the proposed location will not have any significant effect on replacement of the turbo pump, and he does not expect replacement will be difficult to perform after installation of the wall and NHC ducting.  Standing at floor level towards the east side of the TCS space and reaching upwards seemed to be the best way to reach the turbo pump flange bolts.  It was also noted that there was sufficient room in the TCS space for two workers to be in the area.

All ITE and TM4  turbo pumps are started. The east station pumping down is good so far.
