5 SHIELDING BLOCKS HAD BEEN MOVED OUT OF ITE.AIR SAMPLE AND SWIPED FIRST BLOCK AND ITE PIT.NOTHING HAD BEEN FOUND ON ALPHA MONITOR AND OTHER TWO MONITORS.

I DISCONNECTED TM4 IN ITE. ALL WATER LINES HAD BEEN PURGED OUT WITH PRESSURE AIR.

TM#4 with UC#8 has been moved from the east target station to the south hot cell.

TM#4 has been moved from the south hot cell to the north west silo.

TM#4 has been moved from the north west silo to the west target station.

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

TM#4 has been moved from the west target station to the south hot cell.

Ta#42 has been installed onto TM4. The "new" 9 pin connector was not an issue...attually went on better than any other previous one. Leaving the mounting screws loose on the target half allowed use of the manipulator to center the pins and insert them with ease.

TM#4 was checked electrically with and without target on it, see attached PDFs for details.

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.

TM#4 with Ta#42 has been moved from the south hot cell to the conditioning station.

TM#4 with Ta#42 in the conditioning station under vacuum electrical check.

 TM4 with Ta#42 was HV conditioned to 35kV with the optics tray at 17.5kV. There was some vacuum response while ramping but well within normal. Attached is a screen shot and the associated data.

TM#4 with Ta#42 has been moved to the west target station.

TM#4 with Ta#42 has been moved from  the west target station to the south hot cell.

TM#4 electrical check with Ta#42 attached post beam at the south hot cell.

TM#4 with no target has been moved from the south hot cell to the south west silo.

TM#4 has been moved from the south west silo to the south hot cell.

Isaac and I leak checked TM4 HS line with new UCX target. The leak detector base LR 0.0xE-9 atm.cc/sec, base pressure0.0xE-4torr. Isaac sprayed helium  on both VCR connections(5 seconds each) and flushed helium around the target for 6 seconds. No response on leak detector.
