Temperature Controlled Stage
A temperature controlled stage is used when a testing is needed at a temperature higher than that of the base temperature of the cold plate. These can be used in both nitrogen, helium and closed cycle systems. A temperature controlled stage is mounted to the system’s primary cold plate and supported by low thermal conductivity materials such as G-10 fiberglass or stainless steel. The temperature of the stage is controlled to a setpoint temperature with an external temperature controller that is connected to a heater and temperature sensor mounted to the stage. This allows very stable and precise control of the stage temperature.
The thermal contact between the temperature controlled stage and the main cold plate are controlled using a mechanical heat switch. This allows the conductive contact between the main cold plate and the temperature stage to be optimized to reduce thermal load on the system and stability of the temperature controlled stage.
- Precision and stability typically better than +/- 0.005K over extended periods.
- Simple operation
- Can accommodate a wide range of requirements
