  • Spellman (Need power board - Augustine to put in PR)
  • Picoammeter x2? (Pete Francis in hand - sent for fix)

  • Magnets (rack - now on - Riad check)
  • Harp (Tony still to look at electronics)
  • Cathode solenoid - power supply

Happy thing:

  • Cavities (all good)

(2) T-Gun Upgrades

Need a safe gun - no devastating trips. Limit voltage to 135kV

RF cage - Features:

  • HV attaches through the back as designed.
  • G10 plate to support the HV cable
  • Nitrogen flow, also through G10 plate aimed at the back of the hot deck
  • Nitrogen flow, though the top of the cage, aimed at ceramic
  • Dimensions need to be longer than the table to keep E fields on the hot deck lower than 3MV/m (air breakdown)

To Fix/Modify:

  • DC bias supply - set point fix (John Musson)
  • RF Cage (Mark/Fay)
  • Back plate to allow increased cooling (open the hole)
  • Move Xelera spellman to the GTS vault - maybe??? Try upstairs first..
  • Software issues (contact Spellman again)
  • Install new fiber link & check (check CW operation)
  • vortex chiller on nitrogen

Housekeeping:
