摘要
DEPFET pixel sensors consist of a p-channel JFET directly integrated into a high-ohmic n-silicon substrate. They offer a very low-noise performance at room temperature and are therefore of interest for applications in biomedicine, X-ray astronomy and particle physics. Measurements on single pixel devices demonstrating the low-noise potential of DEPFET sensors are shown. The DEPFET pixel bioscope system is based on a 64 x 64 matrix of DEPFET pixels. Measurements of the homogeneity of the charge collection efficiency and of the spatial resolution of the system as well as on the capability of DEPFET sensors to detect tritium with a good efficiency are presented.
