Cryostat Temperature Sensors | 1 | Lakeshore | 224-12 |
NOTE: we have two identical devices (“Spectrometer Lakeshore” and “Cryostats Lakeshore”). The only difference in the control software between the two will be the look-up table which maps the Lakeshore sensor input names (i.e. ‘C1’) to physical sensor locations within KPF (i.e. ‘Echelle’).
Relevant Functional Block Diagram
Spectrometer Lakeshore shown; Cyrostats Lakeshore is the same except the temperature sensors go to the cyrostats.
