TM#3 with NiO#2 has been moved from the south hot cell to the conditioning station.

The module was checked electrically this morning before the module move. See the attached PDF for details.

September 24

 After the manipulator repair Maico installed the NiO#2 onto the target module. Once connected I completed a leak test on the HS line with Isaac. The leak testing cart would not pump down originally (something wrong with the cart) but eventually it did start to work. The cart pumped to its lower limits and did not respond even with the module was flooded with helium. A electrical test was then conducted by myself and and Don Jackson (see attached). During the standard test the Target to Anode and to 60kV common read lower than expected at ~47Momh @ 1kV. Also of note during the conductance check the measurement from c-d was low at 1.82 mohm.

3  additional tests were completed 2 of which were coil to common (both sides). The resisance was measure at 47 ohm with the megger and 1.32 Kohm with the uohmmeter. The coil lines lines were also measured to get and indication of the resistance of a copper line. These lines were measured while they were not jumpered both the coil + and coil - measured 5.73 mohm.

A meeting with Lia and Friedhelm was held and and the decision was to move the module and test it in the conditioning station. Fingers crossed that the module will still work.

Sept 25th

Maico finished installing the cover today for the module to be moved. Other elogs cover the other activities for today.

 Also of note the turbo pumps were started on the conditioning station around 1:30. Don and Travis completed and electrical test, see other elogs. When attempting to start IG1 the controller indicated there was no filament, this gauge only has 1 to start. It will have to be replaced when the module is next vented. In addition to this it appear the PNG1 controller has failed again. I have emailed Dimo to see if we can get one to test. The img100 is new and different cables have been used. All 4 options for connections were also tested in case of a wiring mistake.

Results of the various electrical checks done on TM#3 while at the hot cell since the 27th of September. View PDF for the details.

 TM4 was move by myself and Grant. Move went smoothly, no hang ups.

 There was also a leak check. There was some water remaining in the HS line but once removed the leak cart pumped down to 0.0 x 10-4 Torr and the leak tester was at the bottom limit. There was no response when sprayed with helium

TM#4 with SiC#29 electrical check post beam see pdf for details.

 Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without spraying helium the leak cart responded and peaked at 1.9 x 10^-6 atm*cc/sec. Attached is a picture of the module indicating the line.

Electrical check done on TM#4 with no target, see PDF.

TM#4 with no target has been moved from the south hot cell to the south west silo.

TM#4 with no target was to be moved today but the move was aborted when the crane failed to move in the East - West direction. The crane does not preform this function in either remote or pendant operation.

The SiC#29 CTL target has been taken apart with the help of Isaac and Chad. Electrical measurements were done between Target and Heat Shield as the target was disassembled. Work was done on October 2nd, 4th, 7th and 8th.

The megger showed about 30kOhm at 50V with the following changes

• Bolts for CTL block loosened
• Above bolts removed
• CTL block pulled away from Heat Shield
• CTL block removed
• Heat Shield lid removed
• Bolts for target removed
• Shims between target and insulators

The megger showed about 50kOhm at 100V with the following changes

• Target removed. Measured between cathode restraint and HS.

The megger showed OL at 540V with No 3 insulator removed. A measurement on No 3 insulator while it was sitting on the HS showed 70kOhm at 120V confirming that the insulator can no longer hold voltage.

While taking off the coil retainer plate, Chad noticed that all bolts were not tight.

TM#4 with no target has been moved from the south west silo to the south hot cell.

The containment box was removed from TM4 earlier this morning in preparation for removal of the C2 circuit water lines, their respective water blocks and conductor block.

The C2 circuit (coil 2) water lines and blocks have been revoed from TM4.

Water block jig could not be used as the window water block connection was nowhere near fitting into the jig (IMG_1224 image below) and therefore caused an interference causing the rest of the blocks to not mate with the jig. A different tool that has never been used was implimented and sucessful (IMG_1227 below).

 Sorry about the picture numbering format...new format will be implimented next time.

 TM4 without a source tray was moved from the SHC to the TCS.  All went well.

With the coil line removed an electrical check was done on TM#4 at the South Hot Cell see attached pdf.

TM#1 with UC #7 has been moved from the south west silo to the south hot cell.

TM#1 with no target has been moved back to the south west silo from the south hot cell.
