  • Sheep Chamber
    • Phil has connected the ion pump from the sheep chamber and the ion pump from gun vacuum chamber to the bake pump using flexible hoses.
    • All the ports have been blanked off. The bottom port has now three viewports.
    • It seems that the turbo pump "cube" cart has problems. The rotation speed does not go beyond 1400 Hz, and seems to slow down within a few minutes.
    • We have a second turbo pump but has to be disconnected form the LERF 1/4 CM by Frank Humphry.
    • For discussion today:
      • What we do need for the prep chamber?
      • Phil, do we have the hardware needed for mounting the spider/anode?, Do we want to install a gate valve to the new anode spool piece? or do we mount a blank flange for now? Do we have 2 extra 2-3/4" viewports for the new anode spool piece?

  • Electrode Polishing
    • Bubba is done polishing the shed and the ball
    • He will work next on the front and back-end pieces. I expect to have those ready for cleaning by the end of this week.
    • Then all the pieces will get UHV cleaned, followed with vacuum degassed in Big Blue.
