Cryostat Temperature Control (JQP-7)
This connector is located under the cryostat cosmetic covers, on the top plate of the cryostat to the left of
the sample chamber when facing DynaCool from the front. The “Serial Com” connections are used to
read thermometer calibration data, magnet configuration data, and other cryostat configuration
information. See Figure C-2 for connector diagrams.
