Focal plane module for the data acquisition sensor and the sensor electronics module
The Focal Plane Module (FPM – triangular shape) and the Sensor Electronics Module (SEM) are shown here, both of which are under the responsibility of DLR Berlin. The FPM houses the CHEOPS CCD detector array and the Front End Electronics (FEE). The SEM contains a power supply unit and a processor which is used to control the FEE and to read out data from the CCD. Conductive thermal straps at the rear of the FPM provide the thermal link between the FPM and the radiators that cool the CCD to its operating temperature of minus 40 degrees Celsius. The heat is transferred from the CCD via a heat sink.
