Limit voltage to 135kV

(1) Status

  • Gun assembled with ceramic and blank flange only. Pumping.
  • RF cage complete
  • Back plate modified and hot deck attached in 'run set-up'
  • Electrode assembled and snow cleaned ready for installation
  • GTS clean

(2) Plans

  • PSS cert
  • Run up Xelera spellman connected to gun to 135kV
  • If corona test good... break vacuum and install electrodes

To Fix List (to get GTS running):

  • Glassman PSS Chassis (Service request to Omar - Carlos)
  • LCW Chassis (Coleman today or tomorrow)
  • Spellman (needs further investigation)
  • Picoammeter x2? (Pete Francis in hand - sent for fix)
  • Viewers insertion boxes bad

To Check:

  • Magnets (IOC check)
  • Cathode solenoid - power supply

(4) T-Gun Upgrades

To Fix/Modify:

  • DC bias supply - set point fix (John Musson)
  • Software issues (Karl to contact Spellman again)
  • Install new fiber link & check (CW setting - Mark emailed company)
  • Need RF fiber from Karl for reflected power

(5) Housekeeping

  • Remove JLab spellman
  • Sort out the air and nitrogen lines.
