Pressure around 140 mTorr. The pressure started increasing early November 2nd. Will continue to monitor.

 Backing pressure further increased to ~ 350 mTorr over the weekend. Vacuum group has been informed and will replace the pump this week.

 

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

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.

  • 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.
