List of all settings in the program:

Safety Maximums:

  • He3PumpMaxVoltage Maximum voltage setting for the He3 pump
  • He4PumpMaxVoltage "
  • He4SwitchMaxVoltage "
  • He3SwitchMaxVoltage "

Automatic control settings:

  • ControllerHe3HeaterVoltage, Maximum voltage the controller is allowed to use when heating the He3 pump.
  • ControllerHe3SwitchVoltage, Maximum voltage the controller is allowed to use when heating the He3 switch.
  • ControllerHe4SwitchVoltage, etc.
  • ControllerHe4HeaterVoltage, etc.
  • ControllerHe7StartTemperature, Temperature where the controller starts the control loop for heating the He3 and He4 pumps
  • ControllerHeaterTemperatureSetpoint, Pump heater setpoint, Pumps are heated to this temperature while recycling or cooling down to 4K.
  • ControllerHeatSwitchOnTemperature, Temperature where heat switches are assumed to be in the conducting state.
  • ControllerHeatSwitchSafeValue, If the 2K plate is above this temperature, the heat switch heaters are turned off, since absorbing is useless.
  • ControllerHeatupTemperature, Temperature setpoint used in the Heat up sequence.
  • ControllerHe4StartTemperature, Temperature at which He4 evaporation is started. All He4 should be condensed at this temperature
  • ControllerHe3StartTemperature, Temperature at which He3 evaporation is started, All He3 should be condensed at this temperature.
  • ControllerDisableHeaterHeatSwitchTemperature, Pump heaters are disabled when heat switches are over this temperature, since the heat pumps are then conducting to the 2k plate.
