Edi Dalla Valle from vacuum group replaced the roughing pump TSG:RP1 in the morning. However, the pumping curve showed a leak: see attachment. It was suspected the VCR water line connection between the lid and the base of the target Heat Shield. After venting the chamber found the VCR connection between the lid and the base forgotten finger tight. Tighten it with wrenches and restarted pumping.

 Turned ON the water for the heat shield cooling circuit. Put a lockout padlock on the transformer breaker since Controls work still seems to be underway.

Turned ON the TGHT and ramping it up at a rate of 1A/30sec. Currently it's at 108A.

Temperature measurements in progress for Ta46clone HP-SIS target, wrapped with 3 Ta foil heat-shields . Stopped for today at 360A for the TGHT and TBHT kept OFF.

 Temperature measurements in progress for Ta46clone HP-SIS target, wrapped with 3 Ta foil heat-shields. currently at 496A and the window is OK.

Wednesday, September 14, 2016, 13:57: The pump does not run properly. Attempting to contact vacuum group

Found that the exhaust pipe needed to be disconnected from the pump. Asked plant group (Curtis) to investigate exhaust pipe on the outside of the building, to check if it is restricted again.

Thursday, September 15, 2016, 11:03: Starting turbos

Thursday, September 29, 2016, 11:16: Turbos stopped.

Friday, September 30, 2016, 08:24: Venting.

TP1A tripped off on Fernando, seems the backing pressure got too high. Even with PV1 closed the RP1 pump could not get below 200mTorr. Derek from vacuum group came and had a look, and is swapping RP1 out for one of the vacuum group pumps, then will see if they can repair ours.

Monday, October 28, 2019, 09:22: The local reader indicated 42 mTorr while EPICS showed 51mTorr.

CG1B showed 8.9mTorr while EPICS shows 14mTorr.

After reconnecting CG1A, EPICS shows 16mTorr. Anthony suggest replacing the gauge.

found TSG:TP1B tripped off. Closed TSG:BV1B as pressure at TSG:iG1 was rising. Pressure is coming down again.

Tuesday, June 30, 2015 by AM

Found the control cable not completely inserted. Inserted cable, which tripped TP1A. Started both turbo pumps again.

Tuesday, June 30, 2015, 09:54: Both turbos at speed.

Tuesday, June 30, 2015, 09:56: Stopped turobs. BV1B does not close when TP1B is switched off. Requested Dave Morris to look into it. All remaining BVs close when TP is swithced off in TMS and TSG sections.

Friday, January 29, 2021, 09:11: CANBUS controller was replaced. Quick systems check ok. Sources, HV, & Optics all good.

Friday, January 29, 2021, 10:05: HV & Ramping check.

Friday, January 29, 2021, 10:08:

Friday, October 19, 2018, 10:00 (Approx): Site wide power outage. TS completely shut down. 

Power brought back Saturday

Monday, October 22, 2018, 07:15: Full white out on screens. To restart PLC.

Monday, October 22, 2018, 07:42: Multiple attempts made to restart the PLC. Controls white out continues

Also attempted restart of the Vacuum. All 4 turbo pumps switch back to red on any restart attempt.

The turbo pumps had been manually switched off from the controllers to protect them once the power was switched back on.

Monday, October 22, 2018, 09:28: Turbo pumps restarted.

Monday, October 22, 2018, 11:01: All back except the magnet.

Monday, January 14, 2019, 09:00: Epics white out

Ref: Fault report  11993 (11981 & 11817)

Monday, January 14, 2019, 09:35: Vacuum page came back. Restarted Roughing pumps. All other pages still in whiteout state.

Wednesday, January 16, 2019, 14:05: FEBIAD installed. Turbo pumps on for Beamline side. Roughing Chamber. Vacuum contols working. All else still in 'whiteout'

Monday, January 21, 2019, 10:30: Epics whiteout state ended. IOC Power cycled by Rod N. IG6 timing out? Contact vacuum group.
