Plan for returning from COVID shutdown

  • Work that can begin immediately (June 10th, 2020)
    • Follow manufacturers "Check out" procedure for new power supply which was delivered during shutdown
    • Measure resistance to ground for both coils
    • Install latest new power supply, add additional circuitry (RLC)
    • Test power supplies in both current and voltage control mode
    • MUST check PS output on scope, with and without RF on.
    • LIKE to check PS output on scope, with and without sense wires attached.
    • LIKE to check PS output on scope, with and without additional circuity (RLC).
  • LABVIEW
    • Determine calibrations: Current to field, field direction equation for epics, function generator output vs PS output, ...
    • Update programs. One for voltage mode, one for current mode


  • After the cell is polarized
    • Test NMR in both voltage and current mode
