• 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.

Removed ITW HS and COIL flow rate monitors installed at the beginning of this year. They were installed on these two circuits for testing.They are broken during last run in ITW due to radioactive field.

TM1 has been connected in ITW.  ITW and TM1 turbo pumps have been started. Water is supplied to TM1 only. Everything is good so far.

Five of the ten target we want to measure the fields on were done today. We will finish up on Monday, and the spent target storage spreadsheet will be updated then.

Field measurements on the spent target has finished see the attached PDF for details.

TM3 has been connected in CS. All water supplies are bypassed theTM3 on the top of the service cap. TM3 TP2 was difficult to start. It is started finally after couple of time try.The pump runs fine now. 

TM1 was disconnected in ITW this morning. Heat shield circuit is purged.

NOTE: If there is a problem with the chiller unit (ie Fault 1 or Fault 2), a power cycle may reset the VFDs for the fans and clear the problem. To do so it is necessary to wait long enough for the VFDs to power off completely. The display will first start to flash before going dark. Wait another few seconds before powering the system back up. The chiller unit is located on the ISAC I Penthouse Roof.

A service tech from Daikine was on site today and has cleaned the chiller unit. In the process he also cycled the power which returned the operation back to normal. The tech provided us with manuals for the VFDs. These can be consulted on DocuSharefor looking up error codes.

Fault 1 refers to unit 1 and Fault 2 to unit 2.

NOTE: If cooling is required, the compressors will have to be run manually. Make sure to switch it off again when the water has reached an acceptable temperature.

The staging did not work properly this morning. Dave Morris have been contacted and will look into it.
