|
Chad and I finished the TM4 UCx6 electrical check and leak check at SHC. Leak check result on HS line is good. There is a dead short between "Z" repellor and HS during the first time electrical check. The dead short disappeared after re- installation of UCx 14 target onto TM4. See attachment
Anders and I did another electrical check on TM4 at TCS under vacuum. See attachment 2 |
