Tuesday, September 03, 2019, 15:00. Wire redone. Crosschecked by Arthur Leung. 

Tuesday, September 03, 2019, 15:16: Turbos tripped. TSG:CG1A above 50 mTorr 


Wednesday, September 04, 2019, 09:34 : Turbos on.  After the bakeout it will be better to have TSG:CG1A checked.

Wednesday, September 04, 2019, 09:43: IG1 on 

Wednesday, September 04, 2019, 09:45: RGA on 

Wednesday, September 04, 2019, 12:42 : Waterlines opened. No response on RGA. Vaccum stable @ 3.1e-6 T
