description The system stabilisation system comprises a heat pipe enclosing the radiation detector assembly and is positioned in a dewar flask. A thermo-electric cooler is joined to one end of the heat pipe. The heat exhaust of the thermo-electric cooler is communicated to a heat dissipation device in the form of a fin assembly. A thermistor senses the temperature at the heat pipe. When the thermistor indicates a temperature in excess of that corresponding to a reference signal, a control signal is produced by a control device to cause a power source to operate the thermo-electric cooler to remove heat from the heat pipe to the fin assembly. The vacuum within the dewar flask effectively limits the environmental heat passing to the heat pipe to radiant heat.
