These two lines are passed helium pressure test this morning. The LD base leak rate 0.0 X E-9 atm.cc/sec. The base pressure 0.0 X E-4 torr. Helium pressure 70 psi. applied helium to both line for 5minutes each. No response on LD during the test.

The HV  cover is installed on to TM2 after the connections. The HV key is returned back to B2 level. The TCS Faraday cage is locked.

I let isac opp switched off ITW turbo-pumps. The argon vent valve in electrical room is opened. The ITW argon venting will be started  soon.

Disconnected  TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test.

LD base LR: 0.0 X E-9. Base pressure:0.0 X E-4. 70 psi helium. 5 minutes each circuit.

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits  comparing to before. 

The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time. 

The TCS and TM2 are still under vacuum without venting

Weekly update the TH schedules. See attachments 1, 2,3.

TM2 has been connected in ITW by Dan.M and David.W. All turbo-pumps have been started. Everything is good so fine.

I did a 5KV mega test on TM3.  Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines are ok. See attachment.

Dan and I disconnected TM4 in ITE. HS water lines has been purged.

Bill and Yasmine did the move. Everything is good.

I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good.    See attachment

I wrote all OL to 0  in attachment 1 ohmmeter check. Please See attachment 2 for correction.

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

Bill and Yasmine did the move remotely this afternoon. The move is successful.

TM4 and TCS vacuum system are connected.   Turbo pumps are started.  Everything is fine so far.

I did a helium pressure test on TM4 at TCS with UCX16 target installed on the module. No leak has been found on all using water lines in TM4. See attachment for detail.

It is ready for HV conditioning/ heating. 

Weekly update .

The TM4 and TCS are vented with argon. 

TM4 and ITE are under roughing now.
