The backing pump (TSG:RP1) was replaced yesterday by Anthony Ip. Backing pressure is down to 1 mTorr on TSG:CG1A

Since yesterday around 4pm. Due to attempt to use the TMS:ER0 device.

IOC rebooted this morning. Archivers restarted.

Some additional smaller magnitude excursions have been observed since the fist on on Dec. 12th. See attached plot. 

The computer has been brought over to PC support for diagnostics. 

Hard Drive was found to be corrupted. A new HD will be installed and Windows upgraded to a newer version.

Thursday, January 16, 2014

The PC has gotten a new HD with Windows 8.

Xming and PuTTY installed and configured for access to EPICS controls

Flow and temperature meter previously installed on cooling circuits. See attachment for details.

Typical values at 95 psi in and 10 psi out. Cyclotron off.

Friday, January 24, 2014, 10:49 : Stopped turbos. Vacuum at 2.5E-7 T 

Friday, January 24, 2014, 12:52: Venting

Finished evaluating emittance rig installation.

Friday, January 24, 2014, 14:25: Roughing.

The Cu-tubing for cooling the Turbo pumps broke off during disassembly. New ferrules could not be located on site and may have to be ordered.

The system will be left under roughing vacuum over the weekend.

Cooling for Turbo pumps reconnected.

CuLCW will be shut off tomorrow. Valved off water supply to MB1 and TSG to minimize air into the system. Turbos are off.

• 2x spacers ITD0468 1/8" THK installed to shift the wire scanner screen closer to the wire scanner. (ITD0469 1/16" THK spacers not used).
• Emittance Rig installed. Manually actuated from out -> in -> out position. No interference observed.
• Replaced two insulators on wire scanner screens that broke in the installation process. New insulators kindly donated from ISIS.

The performance of the roughing pump has gradually gone down. Notably after the system has been vented. See attached screenshot from the archiver.

E-fault 7258.

The archiver was not running

 Archiver restarted.

Monday, May 12, 2014, 10:02: Jane R. power cycled the hardware. EPICS is back up. Sources archiver required a restart.

Restarted archivers.

The ground connection between B and F (ISK4523D Rev 6) was found burnt off. It will be switched out as per CATHODE BIAS configuration (ISK4563D Rev 3) by Ray D.
