A Bioscope system based on a 64 × 64 -matrix of DEPFET pixels has been developed for real-time digital autoradiography in biomedical applications. It provides very good energy and spatial resolution at the same time. The DEPFET pixel cells consist o

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

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,

In the DEPFET pixel concept the detected incident radiation is directly sensed and amplified by a JFET integrated in every pixel cell. While the DEPFET detector principle has already been demonstrated previously on single pixel structures, we present

A new kind of silicon pixel detector with integrated amplification has been built and tested. Each pixel consists of a p -channel JFET located on a fully depleted substrate. The pixel size can be customized by using a drift-chamber-like transport mec

Presents an active pixel matrix for high rate, spectroscopic and imaging X-ray detection. It is foreseen as a wide field imager on the XEUS (X-ray Evolving Universe Spectroscopy) satellite. A 1024/spl times/1024 pixel device with pixel sizes of 50-75
Field effect transistors embedded into a depleted silicon bulk (DEPFETs) can be used as the first amplifying element for the detection of small signal charges deposited in the bulk by ionizing particles, X-ray photons or visible light. Very good nois
