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.

to reduce the radioactive shining from  SHC Ta# 40 target.

TM4 has been connected in ITE. All turbo pumps have been started now. The pumping down on TM4 and ITE is good so far. The water interlock check on TM4 is done,and everything is fine. The ITE  IG1 still couldnt be turned on even if we replaced a new TM4  IG1 at CS. The problem is on the connecting cable from ITE to electrical room or gauge controller. I talked with Friedhelm  and vacuum group will be noticed on this problem.

I moved5shielding blocks from ITE to block storage area, This is a job for preparing ITE vacuum surge investigation and leak check.

A huge leak had been found on HS circuit during 60 psi helium pressurize test. Other circuits are free of obvious major leak at present .We will test them again once the TM3 is back to CS. See attachment for details

I moved 5 shielding blocks to ITW this morning .I checked the water signals in electrical room before the moving, and everything is fine. The argon venting systemin ITW and electrical room is ready also.

TM3 has been connected in CS.Three turbo- pumps have been started. The pumping down is fine so far.
