A sensor/support system includes a sensor assembly having a planar radiation detector lying parallel to a reference plane, a readout circuit, and an interconnect joining the radiation detector to the readout circuit. The system further includes a support structure, the support structure having a platform with a first side to which the sensor assembly is affixed and a second side oppositely disposed from the first side. A shim is affixed to the second side of the platform. The shim is made of a shim material different from the detector material and the platform material. The shim reduces the strain in the interconnect when the temperature of the sensor/support system is changed, as compared with the strain in the interconnect in the absence of the stabilization structure. The shim is selected such that an in-plane strain in the interconnect, measured parallel to the reference plane, during a required thermal excursion is less than a maximum strain difference over the thermal excursion for the interconnect material in low-cycle fatigue for a design number of cycles evaluated over the required thermal excursion.
