Post 30-40min unexpected power outage this morning, Steve checked the status of the vacuum and I powered up Chiara.

I brought back the FE machines and keyed all the crates to bring back the slow machines but for the vac computers.

c1vac1 is not responding as of now. All other computers have come back and are alive.

 

 IFO vacuum, air condition and PMC HV are still down. PSL out put beam is blocked on the table.

 We are pumping again. This is a temporary configuration. The annuloses are at atmosphere. The reset reboot of c1Vac1 and 2 opened everything except the valves that were disconnected.

TP2 lost it's vent solenoid power supply and dry pump during the power outage.

They were replaced but the new small turbo controller is not set up as the old TP2 was so it does not allow V4 to open. 

Tomorrow I will swap back the old controller,  pump down the annuloses and close off the ion pumps.

I removed the beam block from the PSL table and opened the shutter. CC4 has the real pressure 2e-5 Torr  

CC1 is not real.

 Tp2 is controlled by old controller. Annuloses pumped down. Valve configuration: "vacuum normal "

  Ion pumps closed at  <1e-4 mT
