New cleaning and polishing pads have been inserted onto the hot cell as well as rubber bungs and a new blank off.

The inital waterblock cleaning with the "scotch bright" pads has been completed. See attached pictures...the first picture being before and the second after.

Tommorow the water block will have bungs put in and a leak check to check the block will take place. After that, the new blank off will be installed and tested.

Bevan and I did a leak check on TM2 tube heater+ from inside service cap in TH. The leak detector base leak rate 0.0xE-9 atm.cc/sec, base  pressure 0.0xE-4totrr. One of side panel on service cap was opened. Bevan sprayed the helium to the "D" line inside the blue insulator.The helium flow was checked , and he sprayed twice. No response has been found on leak detector.  See attachment pictures

  592   Tuesday, February 04, 2014, 09:42 David WangSouth Hot-CellRepairTM2 pressure test on TM2 tube heater +(D) water line.

Chad and I did a pressure test on TM2 tube Heater+(D) water line.I pressurized the D line with shop air from quick connectors(both ends) on service cap.chad applied bubble soap onto the D water block in SHC. The test started from 5psi,and increased 5psi each time to 40 psi. From 5 to 35 psi, no bubble has been found on water block. At 40 psi , bubble appeared from blind blank off seal , but not from soldering joints. Since the o-ring seal for the blank off is  vacuum seal , but not for pressurizing, It is understandable the seal could not hold 40 psi pressure air. No bubble had been found on the D water block soldering joints .See attachment pictures.

Chad and I leak checked TM2 tube heater(+) water line yesterday afternoon. The water line was difficult to pump down on base leak rate, but LD  base pressure was fine . The base pressure on leak detector was pumped to 0.0XE-4 torr quickly. The base leak rate only could be pumped  to  4.5 xE-8 atm.cc/sec after 1 hour waiting time. All vacuum connections to leak detector  in the target hall were leak checked and they were good. Chad checked helium flow in SHC. He sprayed helium twice on tube heater(+) water block soldering joints. I did not see any response on leak detector in TH.The base Leak rate and base pressure did not move up during the test.  See attachment pictures.

The Target Assembly was inspected with Chad, Jens Henning and Anders today.

  • The Target Container was broken.
  • Material was deposited on the Heat Shield around the Target Center Block
  • Material was deposited on the IG-LIS source.
  • Electrical checks to ground (HS)
    • The Extraction Electrode passed the electrical check at 1000V
    • The Exit Electrode (c) held only 40V at 22 kOhm
    • The IG Electrode 1 (f) held 250V at 390 MOhm
    • The IG Electrode 2 (g) held only 40V at 22 kOhm
  • IG 1 and IG 2 both held 250V at 450 MOhm to Exit Electorde (c)
  • No spark marks were observed on the 9-pin connector

  580   Thursday, January 16, 2014, 10:36 chad fisherSouth Hot-CellRepair  East Manipulator Repair

The repair/cable replacement on the east manipulator is now complete.

Yesterday's initail cable replacement went very well however, due to a minor glich, we were unable to test the tong movement until I was out of the hot cell. Tong did not fully close and felt like there was a "hard stop" at a repeatable spot in the  closing of the tong. Upon further investagation, I determined that the problem was definelty on the slave side.

I conducted a troublshooting exercise this morning to narrow down the problem. I quickly found that the new tong came from the manufacture with two incorrect fasteners (socket head cap screws) instead of set screws. As a result the tong was being kept from closing as the head of the socket head cap screws was interfering.

I replaced the SHCS was the set screws from the old tong. The tong now functions with full range of motion.

Jan. 15, 37 minutes in cell .26 mSv

Jan. 16, 16 minutes in cell (as I did some clean up of compressable waste) .05 mSv

Also, the inital repair utilized a prototype tool I designed (and with assistance from Maico, built). This tool made the repair much easier. I will be making small improvements to the design and issuing drawings to the vault and shop.

  578   Thursday, December 12, 2013, 11:14 Bevan MossConditioning StationStandard OperationTM2 HV Chase Electrical Test

While under vacuum Travis and I completed diagnostics of the HV chase. Majority of the lines showed OL at 1kV but there were the following "failures"

A to P @ 250V 716kOhm
A to Q @ 1kV 25.18MOhm
B to C with ohm meter 8Mohm @250V 830kOhm
B to D @ 1kV 15.57MOhm
C to D @1kV 16.18 MOhm
P to Q @1kV 1.069 GOhm
G to J with ohm meter dead short.

Ideally all of these values would be OL and they may improve or get worse when the source tray is installed depending on where the electrical contact is. I need to discuss with Friedhelm but I believe that as these values the module can still operate. Without changing the HV chase there is very little chance of improving these values.
