  • 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)

  717   Monday, July 28, 2014, 14:45 David WangConditioning StationDevelopmentTM2 turned off TM2 and CS turbo pumps.

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

  718   Monday, July 28, 2014, 17:26 Ron KuramotoITWRepair  ITW:IV5 Air leak repair

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.

Repair was done by Dimo Y. who received 0.01 mSv, and assisted by Anthony I. & Ron K. who both received zero dose.
Rad fields measured by RPG were; 1300 uSv/hr above B/L and 350 uSv/hr @ the Solenoid valves at knee height.

  766   Thursday, October 16, 2014, 15:40 Anders MjosConditioning StationMaintenance  Chiller unit

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.
