Abstract :
The DEPFET structure consists of a field effect transistor integrated on high-resistivity silicon, which can be used as a radiation detector. Due to several features (e.g. very low noise at room temperature, information storage capability and a thin, homogeneous entrance window), the DEPFET concept is useful for various applications. In order to apply a DEPFET pixel detector in autoradiography, 64×64 matrices with a pixel size of 50 μm×50 μm were built. Using several ASIC chips for the readout control and signal processing, a complete sensor system allows a row-by-row detector readout with almost continuous sensitivity. First results on the device homogenity, the quantum efficiency and the very promising noise performance are presented.
