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.

Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room.  The gasket between the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully.

ITE Entrance module has been moved from the east station to the conditioning station.

ITE Entrance module has been moved back to the east station.

ITE entrance module is reconnected in ITE.

TM4 are vented with argon and disconnected at CS this morning.

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

  TM1 has been disconnected in ITW.

Chad and I  leak checked the TM1 HS line with new target installed. Base leak rate 0.0xe-9 atm.cc/sec. No any response has been found on LD. The line will be pressurized at CS with helium tomorrow.

TM1 is connected in CS. All turbo pumps are started.

Helium pressure test on TM1 HS water line at CS is done. 80psi helium with LD 0.0xE-9 atm.cc/sec. 3 minutes test and no response on LD. The line is leak tight.
