Two views of the fully integrated Focal Plane Array. The 36 blue CCDs supported on the grey SiC detector plane structure are visible under a protective cover. Below them are two levels of thermal isolation to minimise the parasitic heating of the detectors by the 12 Readout Electronics, which are located below the CCDs (see Figs. 3 and 9) in the body of the Focal Plane Array Electronics Structure. Six Power Supplies for the Readout Electronics are located on two sides of this structure. Spacecraft power is delivered to the connections visible on the Power Supplies, while a SpaceWire data connection to the Control and Data Processing Unit is made to each Readout Electronics in the space below each Power Supply. The harness in the foreground in the lower image is the connection from the Power and Mechanism Control Unit to temperature sensors on the detector plane structure.
