ABSTRACT:
In a cryostat, an isothermal boundary is proximate a large plurality of devices that are being cooled. The barrier is slightly colder than the devices so that heat flux therebetween is very small. The devices are in good thermal contact with a cold plate, which is made of a high thermal conductivity material. A single heater and a temperature sensor control the temperature of the cold plate as heat flows from the cold plate to the isothermal boundary. By limiting heat flow from the cold plate, temperature gradients throughout the temperature controlled region are very small. All of the devices to be cooled are very close to the same temperature. The isothermal boundary is maintained at the desired temperature by a flow of cryogenic refrigerant and a temperature sensor on the isothermal boundary provides inputs to a controller of refrigerant flow. The cryostat is constructed to minimize the amount of energy required from the heater to maintain the temperatures, and to minimize refrigerant flow.
