Two experiments:

The following boxes/instruments need to be constructed for Xuetao in 2019:

Metastable Helium

  • TOF box (detector input may need modification for new MCP)
  • Filament PS for Exciter (? not sure) ~1A for indirectly heated cathode (one fil. end is at Cathode potential)

Regular Helium

  • TOF box
  • Filament supply (same as BU)
  • Quad PS (same as BU)
  • LV pulser (same as BU)
  • some sort of preamp or interface to new MCP (not yet defined)

Older version of list for BU

  • TOF box
    • FPGA board with pseudo-random pulser and TDC; controlled via USB/serial I/F
    • Pulse input from detector preamp (also supplies preamp power)
    • 0..-25V manually adjustable supply for cathode offset (with panel meter)
  • Filament supply
    • Isolated supply, 0-3A constant current (?)
  • HV Pulser / Mixer
  • LV Pulser / Mixer
  • Preamp (MCP)
  • Preamp (Channeltron)
  • E-Gun power supply

On 5/30/19, Michael visited. He says only the first 4 boxes are needed. Xuetao will not use the Channeltron because he has a huge MCP.

For the "Regular" experiment, we use the MCP preamp and LV pulser

For the "Metastable" experiment, we use the Channeltron preamp and HV pulser
