TM 4 had been leak check in ITE due to   relatively high PNG1 and IG1 readings.All TM4 primary and secondary  vessel air to vacuum seals had been leak checked. All water lines in TM4 had been helium pressured . There is no leak had been found so far.

On April 08th, all water lines in TM1 had been helium pressure tested(70psi) at conditioning station. No leak had been found.

TM1 has been reconnected in ITW. Water interlock check for TM1 is done.

I leak checked new installed ITW EXIT1 tank to module o-ring.No leak had been found . Also ,TM1 primary vessel air to vacuum seals had been checked at the same time. There was no response had been found on leak detector.

5 shielding block had been moved  back to ITE. The ITE is configured to take proton beam.

TM3 leak check at conditioning station without target: TM3 all air to vacuum seals have been leak checked . They are all good. Water lines TAR(+-), TUBE(+-), GAS, MSP , COIL2(+-), EE, HS(1,2) , GE,and WINDOW have been helium pressurized to 70 psi for 2 minutes each . No response had been found on leak detector. They are leak tight.. Leak detector BR 0.0xE-9atm.cc/sec, BP 0.0xE-4 torr. TM3 and CS vacuum: PNG15.2xE-6 torr, IG1 8.8xE-7 torr,IG2 2.8xE-6torr, IG1S 1.3xE-6 torr.      

Water interlock check  on ITW is done. All water signals are strong on EL panel.  ITW is configured to take proton beam.

HS had been purged. The ITE is under venting. The TM4 will be moved to SH on next Tuesday which is May 21th.

TM4 Ta#40 HS leak check is done at SHC . No leak has been found so far. There will be  a helium pressure test on it at CS.

TM4 has been connected in ITE. The pumping down is fine so far.TM4 water interlock check was done yesterday.

Dan an I  transferred 5 shielding blocks from ITW to ITE. The ITE is configured to take proton beam.

Dan and I  disconnected TM1 in ITW.

Chad and I leak checked the TM1 UCx target heat shield at SHC. No leak has been found so far.

 I  reconnected TM1 to ITW on 02 July.The pumping down is good so far. TM1 water interlock check is good also.

5 shielding blocks had been  transferred from ITE to ITW.  The  ITW is configured to take proton beam.

TM4 has been disconnected in ITE. All water lines on TM4 have been purged. ITE is venting now.

Leak checked TM3 without source tray in CS this morning. The CS and TM3 vacuum: IG1(top of the TM3 service cap)4.9x E-7Torr, IG2(diagnostic box  primary)1.9XE-6 Torr. IG1S (secondary vessel)7.9X E-7Torr. The leak detector was at 0.0XE-4 torr and 0.0XE-9 atm.cc/sec level during the leak checked. All water lines quick connector fittings, NPT thread fittings, water cap seals, blue insulator seals, bellow, gauges seals, turbo-pumps, all blanket panels,and TM3 to CS vessel seal have been sprayed with helium and leak checked. No leak has been found. The TM3 is leak tight in CS.

CS water cooling and vacuum system have been turned off at 10:00 AM this morning.The TM3 will be disconnected and moved to silo tomorrow morning.

3 turbo pumps on TM4 and CS have been started. The pumping down is good so far, The TM4 PNG1 reading is more than 10 times higher than IG1 which is at the same chamber. It could be a controller problem.  Other 3 high vacuum gauges behavior normal.  The TM4 IG1 is replaced today and it works fine now.

Bevan and I did a helium pressure test on TM4 HS water circuit at CS. The leak detector is pumped to the bottom scale(E-9 atm.cc/sec and E-4torr). We applied 70 psi helium to the HS circuit for 3 minutes .  No response had been found. I also leak checked IG1 flange which was replaced yesterday. It is  good. We connected the TM4 to CS and put the HV cover on. The water cooling system will be started soon.
