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.

I reconnected TM3 in ITE. All turbo pumps have been started. The water supply to TM3 only in ITE. The HV keys are back to electrical room.

5 Shielding blocks have been transferred from ITW to ITE. The ITE is configured to take proton beam.

The TM1 and ITW  were vented with argon gas last night. TM1 had been disconnected in ITW this morning.

Chad and I leak checked TM1 HS waterline with new target installed at SHC. The LD base LR:0.0xE-9atm.cc/sec, base pressure: 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and flushed helium around the target. No response has been found on leak detector. The target HS line is leak tight so far. I will do helium pressure test on this line at CS on next Monday.

I connected TM1 at CS. All turbo pumps have been started. The pumping down is  good so far.

The TM1 HS line is  pressure tested this morning with 70 psi helium  at CS. No response has been found on leak detector.

Stop TM1 and CS turbo pumps and ruff pump. TM1 is disconnect at CS. It will be vented tomorrow morning and moved to ITW.

  TM1 has been connected in ITW . The new roughing pump replaced on last Friday works good. I started all turbo pumps in ITW. The ITW TP1 controller was broken during the starting time. Dimo and I changed a new controller for ITW TP1 in electrical room. The pumping down is good so far. ITW water supplies to TM1 only.      

• TM2 installed in Conditioning Station
• Varian Leak detector connected directly to Target Module 2 Service cap.
• Vacuum draw in Target Station with both module turbo pumps
• Leak detector baseline normal (10^-4 Torr, 10^-9 Std cc/s He)
• Since no Source tray is installed, and tube heater supply conductor is blanked off in target enclosure, it was necessary to test both supply and return points.
• For each line tested, 80 psi He was connected, and waited ~2 min to for a response on the leak detector.
• Lines tested:
  • conductor D (tube heater), Supply -> no He response
  • conductor D (tube heater), Return -> no He response
  • conductor C (tube heater), Supply -> no He response
  • conductor C (tube heater), Return -> no He response
• Based on this leak testing, both supply and return lines of conductors C & D are leak tight under 95 psi He (80 psig He supply to vacuum)

I turned off TM2 and CS turbo-pumps. TM2 will be moved from CS to silo tomorrow morning.

ITE entrance module is reconnected in ITE.

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.

TM4 is connected at CS. All turbo pumps are started. The pumping down is good so far.
