摘要:
The invention relates to a radiation entry window (10) for a radiation detector (2), in particular for a semiconductor drift detector (2), comprising a flat window element (11), which is at least partially transparent to the radiation to be detected by the radiation detector (2), and comprising a window frame (12) that laterally frames the window element (11), wherein the window frame (12) is made of a semiconductor material and is substantially thicker than the window element (11).
摘要:
The invention relates to a radiation detector (1) for detecting low-intensity radiation, especially for detecting individual photons. Said radiation detector comprises a plurality of rows of image cells (5) with respective pluralities of image cells (5) disposed one after the other and respective signal outputs (6). The radiation to be detected generates signal charge carriers in the individual image cells (5), said charge carriers being transported along the rows of image cells to the respective signal output (6). A plurality of output amplifiers (7) are connected in parallel to one of the signal outputs each of the individual image cell columns and amplify the signal charge carriers. The invention is characterized in that the output amplifiers (7) comprise respective avalanche amplifiers (8).
