HV chamber : Replace cathode electrode

  • Electrodes
  • leak test large grain Nb cathode/ceramic/flange assembly : << carlos' logbook entry goes here >>
  • S&A jobs (will walk with Chris Gould 4/7 @ 9am UITF)
  • fiducialize Nb cathode to 10" flange (old method glued fiducials)
  • (maybe) fiducialize existing 10" flange to HV chamber
  • fiducialize anode to HV chamber
  • align cathode to anode
  • align LM to cathode (after venting depo)
  • align HV to chamber Y
  • re-align laser for retro-reflection
  • vent HV chamber, remove cathode electrode, searching for puck tab

Depo chamber : Replace schneedle, fix pucks, opportunistic jobs
