Grant Minor | South Hot-Cell | Repair | TM2 | No target / no source tray | Leak check on TM2 ionizer tube cooling lines C and D - module side |
Target Ionizer tube cooling lines "C" and "D" in Target Module 2 were both leak checked at the Hot Cell. The lines were both blanked-off.
Bill Paley was present with David Wang in the Target Hall, operating the leak detector. Grant Minor and Anders Mjos were present with Chad Fisher at the Hot Cell.
The "D" circuit was already blanked off with a copper blank containing silver brazed stainless steel inserts and indium plated inconel c-seals.
The "C" circuit was already blanked off with an aluminum blank and rubber o-rings.
The cooling lines are indicated in the attached screencapture from ITA6021 Rev .14, and are also labelled in the attached photo.
The "D" circuit was checked first, starting at around 12pm.
1. The helium flow was tested by blowing dust on the work table.
2. The base leak rate on the Varian leak detector was confirmed in the "D" circuit to be stable at 10^-9 atm cc / sec and the pressure was 10^-4 Torr.
3. Each soldered joint on the "D" circuit was sprayed with a 2-second blast of helium - no response at the Varian.
4. The joint between the module-half of the water block and the copper blank-off was sprayed with a 2-second burst - no response.
5. A general area flood of helium sprayed for 10 seconds was applied all around both the "D" and "C" blocks - no response.
It was concluded that the "D" circuit had passed this leak check. The "C" circuit was checked next. The detector was changed to the "C" circuit and the circuit was pumped down. At around 2pm the leak check resumed.
6. The base leak rate on the Varian leak detector was confirmed in the "C" circuit to be stable at 10^-9 atm cc / sec and the pressure was 10^-4 Torr.
7. The solder joint area on the "C" circuit was sprayed with an 8-second burst of helium - no response.
8. The joint between the two halves of the water blocks was sprayed with a 6-second helium burst - no response.
It was concluded that the "C" circuit had passed this leak check.
The electrical continuity of the "C" and "D" circuits were confirmed in the Target Hall at the service cap, and in the module at the Hot Cell, to double check that the correct lines has been pumped and leak checked - this was OK.
The ionizer tube heater lines appear to be leak tight at the Hot Cell.

chad fisher | South Hot-Cell | Standard Operation | TM3 | SiC#30 | SiC#30 Removed and inpect |
SiC#30 has been removed from TM3. A quick exam of TM3 source tray did not yield any obvious signs of damage.
9 pin connector on the target showed the usual sparking/arcing marks.
Heat shield has been removed from the target. Inside of heat shield has some unusual marks on it and quite a lot of black deposits.

David Wang | South Hot-Cell | Standard Operation | TM4 | Ta#44 | Leak check on TM4 HS water line with new Ta#44 target. at SHC |
This morning Chad and I leak checked TM4 HS line with new Ta#44 target installed. I calibrated LD before the check. Before check, the LD base LR 0.0xE-9 atm.cc/sec, base LP 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and did a flush around the target. There is no any response had been found on LD,. The line is good on leak tight. with spray method. No helium pressure test on the HS line at CS since TM4 was moved back to ITE directly. |
