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.

SMP  vacuum pumping down is stopped. SMP and TM4 venting to atmosphere will be started soon.

December 5, 2024 - Aaron Tam w/ help from Chad, Peter and Adam at the Crane  

Hot Cell Prep:

• Tools organized, working space cleared, spot for clean tool to sit placed, Air tool is open and spinning clockwise for tightening 

Loading:

• Ta#68 was loaded into pail# 300
• PEEK seal parasitic assemblies loaded (PEEK seals were removed in ID: 2724)
• Farran had some old samples that also went in (More details to come when Farran sends the info)

Lid/latching:

• This went smoothly

Bail attachment:

• Some difficulty in attaching the Lifting Bail, but went on smoothly with the help of Chad

Notes:

• One of the PEEK seal parasitic Target assembly lids was missed in the loading. This will have to be loaded next time. 
• All parasitic type targets remain in the yellow container shown in photos below.

USB was discovered to be in the reverse direction and will need to be change around to become operational

01/Dec/2020

USB was pulled from conduit

While attempting to re-pull the USB in the correction direction, the ethernet cable was damaged and need to be replaced,

(thanks to the Hubert's team for the wire help) 

It was decided that it was too problematic to re-pull the wires with all other wires in the way. Therefore all the wires were removed from the operator control panel, and pulled so that the USB, USB power cord, and ethernet could be re-pulled all together.

However, even once all the wires were re-pulled and reconnected it was discovered that the USB had become damaged, and was removed again.

23/Dec/2020

- A new conduit was added through to the NHC, for only the USB

- USB was fed through, reconnected, and tested

- Putty will need to be added around the conduit to ensure a good seal into NHC

 I moved 5 shielding blocks from ITE to ITW .  I checked  all ITW water signals strength and frequency in electrical room, and everything looks fine.The ventilation system is set up for ITW. MAA is locked. ITW is ready for taking proton beam.

Frank and I replaced ITW Exit module 1 side square service panel o-ring seal. Also, The target module pit top flange o-ring seal in ITW pit is replaced.  

ITE entrance module has been disconnected and the lifting yoke is installed for module move. See attached pictures.

Today (2024-07-05), five flasks were loaded in preparation for shipment with the following targets: SiC#43 (Pail 272), SiC#44 (Pail 275), Ta#63 (Pail 266), UC#40 (Pail 278), UC#38 (Pail 274).

The crimped lifting loop has been applied to each pail. The locks have not yet been applied to the flasks at the time of writing this log, but will be done next week.

The mini-storage vault is now EMPTY. Because some of the pails had contamination (200 - 1500 CPM), it is highly recommended that the mini-storage vault be cleaned or at least swiped for contamination.

The target index spreadsheet has been updated (attached).

An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Travis Cave, Riley Sykes, Maico Dalla Valle, and Jason Zhang as per Work Permit  I2024-07-10-1. The following items were checked:

• Check condition of wiring for physical/radiation/UV damage
  • OK, no signs of significant damage
• Check for cable tray debris or damage
  • There were multiple items in the cable tray which do not belong there - misc. pieces of wood and metal... these items were not disposed of but should be in the near future
• Check inside control panel: components and wiring, labeling
  • Labeling intact, components in good condition
  • Misc. random wires pulled to check... OK
• Verify camera views
  • This was not inspected in detail as it is something that would be done prior to remote operation
• Check connectors for damage
  • All connectors OK
• Check pendant for damage and verify labeling intact
  • Pendant OK
• Lid open/close test
  • Lid was opened and close multiple times - smooth operation, no concern
  • Lid close logic was checked - OK
• Vessel rotation and limit switch check
  • Both CW and CCW limits were checked, functioning
  • No concern on rotation - chain drive, rotary limit switch, and cable reel all functioning normally
• Lubricate chains
  • Not done - should be done next year
• Inspect tensioners
  • Done - OK
• Tighten fasteners
  • Not all fasteners were checked - washers will be replaced soon so this was not deemed necessary
  • Approximately 50 washers are missing for socket head screws in slotted parts. Not safety critical but they should be replaced soon.
• Visual inspection
  • All OK

Overall the inspection was successful.

The annual inspection of the main storage vault will be skipped this year since extensive inspection and testing was performed during the re-alignment job in May (see this e-log for details: e-log 2584). This included successful testing of the emergency close mechanism.

The mini storage vault was informally inspected by Adam Newsome on 2024-06-18. The following was checked:

• Cabling and cable management
• Connectors (note: the strain relief for the remote control input cable was loose - it was tightened)
• Controls box - external connectors and wiring
• Limit switches - wiring, mounting
• Motor visual check
• Drive wheels visual check
• Drive track visual check (note: the track had small pieces of metal shavings on it which were wiped off)
• Bearings visual check
• Miscellaneous fasteners visual check

Photos can be found in G:\remote handling\Facilities and Projects\ISAC\Mini Storage Vault\Inspections

The inspection was generally successful. No areas of concern. Regular inspection will resume next year.

The annual inspection of the mini-storage vault and main storage vault was completed June 23, 2023. The following items were checked:

• Cabling and cable management
• Connectors
• Controls box - internal wiring and components, functionality
• Limit switches - functionality, wiring, mounting
• Motor
• Bearings
• Set screws
• Miscellaneous fasteners

The inspection was generally successful. A couple of minor findings were:

• Bearings for both the main and mini storage vaults must be greased. This is planned for a different day as it involves removing the mini vault's door.
• There was a small piece of metal on the track for the mini storage vault which was causing the door to "bump" over it as it passed over. This piece was removed and the door behaved normally.
• The wheel track for the main storage vault was dirty - it was cleaned
• It was suggested that the 120 VAC power cable for the mini storage vault controls box should be connectorized - this will be added to the "to-do list" for the future

Annual ITW water signal interlocks check was done with TM2 in ITW.   Water signal interlocks on all water circuits related to TM and 2A beam lines in ITW work fine. 

ITW is configured to take proton beam.

 5 gallon spent target pail, lifting long pole and hook assembly load test was done by Rupan, Keyur ,and David.  Load in pail 101 lbs, test time 10 minutes. No deform on pail( pail OD 29.8mm is not changed before and after test.  The test passed. Also 50 lbs load test on empty tray transit frame was done. The frame is good on test.  Rupan will have a test report on this job.

I found primary vacuum back up pressure ITH CG1, CG2, and CG4A were unusually high this morning. They should be about 10 -20 mtorr after one night pumping, but all of thier reading were 340-350-mtorr. Thease cause the current draw on primary turbo pumps were all over 2.0A(should be about 1.0A). I let Paul closed all BVs on primary side . The pressure dropped quickly to normal range after all BVs were closed. This shows the back up line are good. The problem are from   one of  the connections  on primary BVs. I let Paul opened the BVs one by one,but the problem did not show again. Now ,the current draw on the turbo pumps are back to normal also.

I will keep monitoring the system and take a look on all KF25 clamps on BVs once I have a chance to access to ITW.

Three manual valves are closed on TCS water system return line in experimental hall. See attachments. It is for TCS TK2 water level slow drop trouble shooting.  These valves will be opened again right after troubleshooting.  

TCS TK2 water level no change(11.1 inches) in this week after valves are closed. I will keep these three valves closed for one more week.

I opened these valves. In two week times, The TK2 level dropped 0.1 inches. The water level change could be a result of evaporation of water in system. We will keep watching on it.

I connected TM4 and CS vacuum system after TM4 move. CS roughing pump was started first this morning. Later, Anders, Bill and I started 3 turbo pumps on TM4 and CS. The pumping down is good so far. The CS vacuum system ion gauges are turned on also.

Requested by Aurelia, and approved by Friedhelm, TM3 service tray cover plate ITA2108 has been remove out of the module. The plated is checked for active and contamination after removal. Then,It is double bagged, sealed ,  tagged, and placed downstairs in TH between south wall and green block . The ram contact reading on the plate is about 10 usv/hr.  We will do anther TM3 HV test at TCS without this cover plate.

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.

On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems  for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak rate:0.0 XE-9 atm.cc/sec, base pressure:0.0X E-4 torr. The circuit which I checked are :TA+, Ta-, Tube+, Tube-, PQ (coil 2), RU( coil1), EE, MSP, GE. The HS and window circuit are opened at this moment so they can not be checked.
