Pressure around 140 mTorr. The pressure started increasing early November 2nd. Will continue to monitor.
Tuesday, November 12, 2013, 09:51 UPDATE
Backing pressure further increased to ~ 350 mTorr over the weekend. Vacuum group has been informed and will replace the pump this week.
|
The backing pump (TSG:RP1) was replaced yesterday by Anthony Ip. Backing pressure is down to 1 mTorr on TSG:CG1A |

Anders Mjos | | | | | | | In progress | Testing impedance with the new TBHT P/S | Wednesday, December 04, 2013, 09:21 : Turbos stopped. Vacuum at 1.2E-7 Torr

Wednesday, December 04, 2013, 15:26: Vacuum at 5E-6 Torr
Thursday, December 05, 2013
Impedance measured on TGHT and TBHT (~2.5 mOhm and ~2.0 mOhm). Readback on TBHT gives an impedance of ~2.5 mOhm. This is higher than the previous test. Local current on TBHT shows 60A more than the readback at 300A. The vacuum did not come down as low as usual, which likely means there is a leak.
