TCS leak check: TCS IG1S1.6 XE- 6 torr. LD  0.0XE-9atm.cc/sec.We used a long pole to spray helium to TCS vacuum seals on diagnostic box and vessel body. Lots helium have been sprayed around the check area.  no leak has been found.

Entry  Thursday, March 04, 2021, 16:30, Isaac Earle, North Hot-Cell, Development, , , NHC gas delivery lines leak checked 

 The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today.  5psi helium gas was applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to the matching connector inside the cell.  The end of the wand was sealed using tape.  The Agilent G8601 leak detector was used on "sniffing" mode to check for escape of helium gas from all joints and connectors.  With the sniffing line attached the leak detector test port pressure was 3.9E-1 Torr and the baseline leak rate was 1.7E-6 Torr*L/s.  There was no response while testing all of the three lines.  For all three there was a leak detector response after disconnecting the Staubli fitting, which confirmed that the lines were properly charged with helium.

Entry  Friday, March 05, 2021, 09:12, Matthew Gareau, North Hot-Cell, Development, TM3, , Containment box door removal and swivel arm test Containment_door_arm_testing_on_TM3.jpg

First thing I entered into the NHC to install to the target kart mounting clip, and remove excess tools and materials from the hotcell

After the TM3 without a target was lowered into the NHC.

Once inside, with the use of the manipulators, I was able to remove the containment box door, place it on the swivel arm, move the arm out of the way, after the door was return to the containment box and reattached.

Entry  Monday, March 15, 2021, 13:01, Isaac Earle, Crane, Development, , , Plate & pin lift assembly load testing (ITA6550) 11x

In mid-2020 design analysis was completed on the steel plate & pin assemblies (ITA6550) used to connect the ISAC target hall crane hook block to the module lifting yoke assembly ITA0494.  The released design note is Document-184431.  

In November 2020 fabrication was completed on two full plate & pin assemblies (photos attached below).  As per the relevant ASME standards (identified in the design note), each assembly has been identified with serial numbers (#1 and #2).  Material test reports for the steel plate and round bar material used for fabrication are attached in PDF format.  For both materials the tested tensile yield strength (from the MTR) exceeds the value used in design calculations (from Document-184431):  117ksi vs 100ksi for the plate material;  138si vs 103ksi for the round bar material.

On February 8, 2021 both plate and pin assemblies were load tested by David Wang and Frank Song.  The total load applied to each was 31,400 lbs (as per the ISAC target hall crane load cell) which exceeds the 125% of rated capacity (31,250 lbs) required for the test.  The lifts were conducted successfully and no deformations or other damage to the assemblies were observed.  Photos of the load test are also attached.

Both plate & pin assemblies are now certified for use up to their rated capacity.  As specified on drawing ITA6550 and in Document-184431, a monthly visual inspection must be performed to check for structural deformation, cracks, excessive wear, and loose or missing fasteners.  In addition, an annual inspection must be performed to check for structural deformation, cracks, excessive wear, loose or missing fasteners, and missing or illegible markings or safety labels.  A written record of the annual inspection must be documented and kept readily available.

Entry  Wednesday, April 21, 2021, 11:18, David Wang, Cooling, Maintenance, , , Refilling high active wtaer system and starting HA water pumps.  

High active water system is refilled. Air are drained out of  system before pump to be started. Following sequence are used to bring the whole system back to operation:

1. close ITE , open ITW. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITW.  Switch off pump when system pressure is stable above 100 psi.

2. Close ITW, open ITE. Switch on the pump. Only 2A beam line related 5 water circuits are in loop in ITE. Switch off pump when system pressure is stable above 100psi.

3. Open ITW, Open ITE. Switch on pump. both ITW and ITE beam line related water circuits are in loop.  Switch  off pump when system pressure is stable above 100psi.

4. Close ITE open ITW.  Bring ITW  target module water circuits back to loop by connecting bypass fittings on to circuits. Only bring one circuit back to system at first. Switch on pump. Wait for system pressure stabilized. Then Close ITW. bring next circuit back  to system.  Open ITW .  wait for pressure stabilized.  repeat the process until all water circuit and connected with bypass fittings in ITW.

5. Check possible leak on valves, fittings, and flow sensors in ITW pit.

6. Go to electrical room, check all ITW water signal status.

7. Close ITW, Open ITE. Repeat same procedure as step 4 on ITE target module water circuits.

8. Check possible leak on valves, fittings and flow sensors in ITE pit.

9. Go to electrical room, check all ITE water signal status.

10. Open ITW.  At this stage, full ITE station and half of ITW station water circuits are in operation.  Check possible leak on pumps, valves, fittings, gauges on water station at TH west end.

11. Keep system in operation. Watch on - tank level , system pressure, and conductivity on resin circuit and whole system.
