 Tuesday, July 17, 2018, 14:34 Increasing current limin on anode to 52.00 mA

Tuesday, July 17, 2018, 14:35 Closing Neon Valve

Tuesday, July 17, 2018, 15:02 FC6 stable

Tuesday, July 17, 2018, 15:02 Opening "Argon" bottle

Tuesday, July 17, 2018, 15:21 Fc6 stable. The present current lies between the on/off Neon Valve.

Tuesday, July 17, 2018, 15:30 Opening Neon Valve

Tuesday, July 17, 2018, 15:51 Re-tuning. Taking a mass scan.

Tuesday, July 17, 2018, 15:55 Checking the RGA, I noticed that the maximum reading for Neon was 7.05e-8T, and for Argon, 6.15e-7T

Tuesday, July 17, 2018, 16:45 Increasing Anode current limit to 100mA. Increasing TBHT to 347A, 361.8 RB, 353 PS. Vaccum ok@7.87e-7T

Tuesday, July 17, 2018, 16:54 Finish for today.

Wednesday, July 18, 2018, 16:02 Closing Argon bottle.

Wednesday, July 18, 2018, 16:08 Closing Neon bottle.

Wednesday, July 18, 2018, 16:13 Measuring what it looks to be a potassium signal. Let's see if the signal decreases overnight.

Friday, July 20, 2018, 11:48: FC0 put in place & the gas lines closed. - Aaron S.
