CP4 is cooking along. Smells real good at mid-y now. I forced the enclosed air temp to rise faster than 1C/hr for several minutes to test ROC alarms, which we found work as intended, along with max temperature alarm. The setpoint is now 110C (TC#1 measuring 76C now, with some fluctuations due to testing). We will continue to monitor overnight with assurance that we have text alarms to help out.

The Y1 arm pressure is increasing. GV11 and BSC replacement spool are relatively wet compared to beam tube and thus outgassing. We discussed closing GV10 and valving in main turbo (and small IP below CP1); still contemplating that (WWJD?). May take action if/when Y1 pressures exceed the turbos ultimate pressure (~5e-8 Torr). Alarms for Y1 have been adjusted to 5e-8 Torr setpoint. CP4 pressure raised to 5e-5 Torr. 

 Bubba turned the VEA chiller on this morning to help control room temp. It was approaching 70F.
