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.

 The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that reset the bias PS and another one  after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem.

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.

TM#1 with UC#9 has been moved from the south hot cell to the conditioning station.

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.

TM#3 with SiC#30 has been moved from the south hot cell to the conditioning station.

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.

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.

TM#2 has been moved from the south hot cell to the conditioning station.

• 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 has been moved from the east station to the conditioning station.
