I connected ITW  vacuum system to TM4. TM4 and ITW turbo pumps have been started successfully. The pumping down is good so far.

With TM4 located in ITW, All air to vacuum seals  on ITW primary and secondary vacuum vessels have been leak  checked with leak detector hooked directly onto the TM4 service cap.The base LR :00xE-9atm.cc/sec. The ITW IG1 was 1.16xE-6 torr which was good. No leak has been found during the checking.Also, the TM4 water lines(except HS) had been  pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITW and TM4 are good on leak checking.See attachment pictures

Chad and I leak checked TM4 HS line with Ta#42 target on the module. The leak detector base LR 0.0xE-9 atm.cc/sec, base pressure0.0xE-4 torr. Chad applied helium to the joints, and flushed the helium around the target. No leak has been found.I will do helium pressure test on this circuit at CS later.

This Monday morning, Chad and I leak checked heat shielding circuit on TM3 with new target installed. The base LR on LD :0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. Chad sprayed helium twice on the VCR joints. No leak has been found. The circuit will be pressured with helium at CS.

The helium pressure test on TM3 HS water line with new Ta target is finished at CS. The circuit is leak tight.. No any response on LD. See pictures.

I reconnected the entrance module back to the ITE station. All diagnostic cables, turbo- pump, air lines, water lines on ITE entrance module and BL2A3 window are connected back.

ITE target module flange seal has been replaced.The flan surface and the o-ring groove have been cleaned with Acetone before the new seal is installed. See attached picture.

ITE entrance module has been disconnected and the lifting yoke is installed for module move. See attached pictures.

ITE entrance module flange seal had been replaced yesterday.The flange and the seal groove were cleaned with Acetone before the new seal is installed. See pictures

ITE TM3, entrance module, and 2A3 window flange seals have been leak checked this morning after 2 new seals replacement.The LD base leak rate was 0.0xE-9 atm.cc/sec,  base pressure was 0.0 XE-4 Torr. I sprayed lots helium around the TM3, entrance module and 2A3 flange seals. No any response had been found on LD during the  spraying. All three flanges are sealed perfectly now.

Anders and I opened the HV cover in ITE and did  a visual check inside ITE HV  cover and top of TM3.Bill was with us and took the pictures. There was nothing obviously wrong when we opened the HV cover in ITE. We disconnected TM3 high current cables from ITE. Then we did an electrical check on TM3.The TM3 was good and passed megga test (465Mohm at 500V). The module was good and was separated electrically from the ITE at that moment. Then, we went back to electrical room and measured the resistance between bias and ground with ground bar opened and power supply disconnect. It was still shorted at that moment .We thought the short is located inside HV chase between electrical room and ITE. Then, we went back to ITE again and reconnected TM3 back to ITE. We wiped two blue nylon insulators between bias and ground, and no obviously spark track or dirty on them. We put HV cover back in ITE locked area, and went back to electrical room again.We decided to do a final electrical check there. We thought the short should be still there and we just want to confirm it . But this time the short  is gone. Everything goes back to normal.   The short disappeared and We test bias to 5KV and the current looks normal now.  

Chad and I leak checked TM1 HS and UC9# VCR fittings. No response had been found on leak detector during the test. I will do helium pressure  test on it at CS later.

TM1 and CS turbo pumps have been started. The vacuum readings are fine on all gauges.

TM1 HS line helium pressure test and TM1 electrical check at CS under vacuum are finished. Everything is good. See attachment

The CS and TM1 is still under vacuum. They will be vented with argon tomorrow mornig

TM1 will be moved to ITW this morning.

TM1 has been connected to ITW. It is pumping down in ITW with 6 turbo-pumps on.

5 shielding blocks have been transferred from ITE to ITW. ITW is configured to take proton beam. Argon venting system for ITW is ready also.

Chad and I leak checked the TM3 HS water line with new target installed.  No leak has been found during the check. Leak detector base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. The line will be helium pressurized at CS later.

TM3 HS water line helium pressure test is done at CS. 70 psi helium , 3 minutes.Base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr.  No response. The line is leak free.
