5 shielding blocks have been moved from ITE to ITW. ITW is configured to take proton beam now.

Grant and I replaced the conditioning station broken  srcoll pump with a refurbished scroll pump which is supplied by vacuum group. The replaced pump is bagged and waiting for RPG further survey in target hall . The target hall is survey after the job, and everything is fine.

I disconnected TM4 in ITE this morning. The heat shield circuit has been purged with air.

TM4 heat shield helium pressure test and electrical check were done  at CS  last week. The results are good. NO leak had been found on heat shield circuit.The electrical check is also good.

Bevan and I transferred five shielding blocks from ITW to ITE. ITE is ready for taking proton beam.

Bevan and I disconnected TM1 in ITW this morning. The TM1 was moved to south hot cell later.   

Chad and i did a leak check on TM1(Lp-TiC) heat shield water circuit at south hot cell. There is no leak had been found on it. The circuit  is leak tight at present. I will do  helium pressure check on this circuit at  conditioning station once the vacuum is good enough.

TM1 TiC #3 target  heat shield  helium pressure check  is done at conditioning station. Applied 80 psi helium to HS circuit for 5 minutes . There is no response had been found on leak detector. The leak detector base LR 0.0x E-9 atm.cc/sec, and BP 0.0xE-4 torr. CS and TM1 vacuum are at low E-6 torr range. The HS circuit is leak tight.

I connected TM1 in ITW yesterday. Everything is good so far. Travis was with me when i did the job.

I changed ITE dump water circuit flow wheel due to its poor performance. The new flow wheel works fine. The signal on electrical board is strong and constant. One shielding block on ITE was moved out for the job, and it has been moved back after the job.The ITE is ready to take proton beam. Travis was with me when i did the job.

I disconnected TM4 in ITE. All water lines had been purged.Travis was with me .

I moved 5 shielding blocks from ITW  to block storage area for preparing the TM1 disconnection. Air sampled and swiped blocks and ITW and everything is fine.Fiona was with me all the time during the moving.

TM1 has been disconnected in ITW. All  water lines had been purged. Travis was with me during the job.

I replaced all high active water system magnetic pedal wheels in ITW and ITE. This is a preventive maintenance job we planned for this winter shut down.

I connected TM 1 vacuum system in ITW. The TM1 and ITW will be pumped out for shut down routine leak check.

Chad and i did a leak check on TM4 heat shield circuit with installed dummy target at SHC today. The leak detector is pumped to 0.0xE-9atm.cc/sec.Chad sprayed helium twice on each  VCR joints .There is no any response had been found on the leak detector during each 45 seconds waiting time. The TM4 heat shield circuit with dummy  target is leak tight so far.  

2013 winter shut down ITW-TM1 primary vacuum vessel, secondary vacuum vessel, and water lines leak check: connected leak detector to TP2(primary and water lines) and TP4S (secondary). base leak rate 0.0xE-9atm.cc/sec,base pressure 0.0XE-4torr. Sprayed helium to all primary vacuum seal and there is no response on leak detector. Helium pressurized all water lines(except HS) at 70psi ,3mins.Tube heat(+) no response, tube heater(-)1.6xe-9atm.cc/sec, target oven(-)5.8xe-9atm.cc/sec, target oven (+) 6.9xe-9atm.cc/sec, EE 5.7xe-9atm.cc/sec, MSP no response, window 7.5 xe-9atm.cc/sec.All water lines are water leak free.  Two leaks had been found on secondary vacuum vessel. One is on exit 1 to tank o-ring (east side, E-N corner). The leak detector got   responses from 1.4 to1.7 xe-7 atm.cc/sec scale . The test  hadbeen repeated 4-5 times and   confirmed the location   . The second one is a small leak which  is on exit 2 to tank o-ring(east side, close to E-N corner). The leak detector got  responses from 1.4 to 1.8xe-8atm.cc/sec scale. The test had been repeated 3 times and confirmed the location. As the present plan. we will replace the exit1 to tank o-ring during this year shut down time.

Edi and I replaced the broken ITH MP1 in target hall with a new pump. The old pump was leak on oil. There were no oil had been left in the old pump by checking the sight glass.Thats the reason of  the pump  failure.The tray which the old pump sat on was full of leaking oil ( highly contaminated ). The old pump was bagged in 3 thick plastic bags ,and the tray was cleaned before the new pump was installed. The working area had been cleaned up and surveyed couple of times after the job. Everything is good. The new pump had been tested after the installation. It works fine.

Disconnected EXIT1 in ITW. All cables , wires and air lines are label marked.

Bevan and I replaced TM4 TP1 today at conditioning station .The pump will be started this week when I do ITE and TM4 leak check .
