Abstract
A circuit arrangement is disclosed for a detector. In at least one embodiment, the circuit arrangement includes a directly-converting semi-conductor material and pulse-shaper in the signal readout electronics assembly. A method is disclosed for a readout of count impulses generated in the semi-conductor material, wherein part of the pulse-shaper is equipped with a relatively longer shaping time constant and a different part of the pulse-shaper is equipped with a relatively shorter shaping time constant.

A circuit arrangement for a detector for ionizing radiation, comprising:
- a plurality of radiation-sensitive sub-areas, each including a directly converting semi-conductor material provided as a radiation-sensitive material;
- and
- a plurality of dedicated readout electronics assemblies, each assigned to a respective one of the plurality of radiation-sensitive sub-areas, to individually read each respective one of the plurality of radiation-sensitive sub-areas, each of the plurality of dedicated readout electronics assemblies including at least one pulse-shaper, one part of each of the at least one the pulse-shapers being equipped with a relatively longer shaping time constant and a different part of each of the at least one the pulse-shapers being equipped with a relatively shorter shaping time constant.
A method for detector elements, pertaining to a directly converting detector for ionizing radiation, the method comprising:
- dividing up each of the detector elements into at least two separately detectable sub-areas;
- and
- assigning a dedicated measurement electronics assembly comprising a pulse-shaper to each of the at least two separately detectable sub-areas, each of the pulse-shapers being configured to convert an equal charge amount of a signal, irrespective of a shape and height of a signal curve generated by the charge amount, into signals of a same level and shape, and at least one of the at least two separately detectable sub-areas of each of the detector elements being assigned a pulse-shaper including a relatively longer shaping time constant and at least one other at least two separately detectable sub-areas of each of the detector elements being assigned a pulse-shaper including a relatively shorter shaping time constant is detected.
A detector, comprising:
- a plurality of detector elements distributed over a two-dimensional surface of the detector, each of the plurality of detector elements being configured to measure a beam, and each of the plurality of detector elements being subdivided into at least two radiation-sensitive sub-areas, at least one of the at least two radiation-sensitive sub-areas within each of the plurality of detector elements being equipped with a pulse-shaper including a relatively longer shaping time constant and at least one other of the at least two radiation-sensitive sub-areas being equipped with a pulse-shaper including a relatively shorter shaping time constant.
