SCSO Cryostat
The superconducting cavity must be maintained at constant temperature and pressure to prevent fluctuations in the resonant frequency. The cryostat has three temperature controlled stages, and is able to hold the temperature below 2 K with nanokelvin stability.
The cavity may also be filled with a test fluid (such as liquid, superfluid or gaseous helium-4) for density measurements at arbitrary temperatures between approximately 1.8K and 5K.
