|
ITW primary and secondary vacuum vessel leak check for 2025 shut down has been done. Also,TM4 internal water line helium pressure test has been
finished. Both results are normal. There are two small old leak on EXit 1 and Exit2 module top plate o-ring under 1Xe-8 atm.cc/sec which we
knoew in past years test. resin spray on leak area reduce the leak ratee below 5Xe-9 atm.cc/sec. No concern on these small leak. See attachment |

Thursday, January 16, 2025, 14:21, David Wang, Conditioning Station, Standard Operation, TM3, No target, TM3 electrical check at TCS under good vacuum
|
A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter
check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern. The rest things are good.
