Abstract
A CdTe or CdZnTe radiation imaging detector and high voltage bias part for applying a high voltage to the continuous electrode to ensure stable performance of the detector. The high voltage bias part includes conductors of >30 um diameter and preferably selected from a group of materials that do not oxidize easily or oxidize less than aluminium.
Claims20
A x/gamma ray radiation imaging/radiation detection, direct conversion, compound semiconductor detector assembly, comprising:
- an x/gamma ray radiation imaging/radiation detection, direct conversion, compound semiconductor detector having two major faces, a first major face for reading out an electronic signal created in response to incident x/gamma ray radiation and a second major face for applying a high voltage;
- and
- a high voltage biasing means connection on the second major face providing high voltage biasing to produce an electric field inside the detector,
- wherein the bias means connection comprises one of the group consisting of i) a conductive wire having a contact face of more than 700 um2 in area, and ii) a conductive wire which has a diameter of more than 30 um.

A ray radiation imaging/radiation detection, direct conversion, compound semiconductor detector assembly, comprising:
- plural ray radiation imaging/radiation detection, direct conversion, compound semiconductor detectors,
- each detector having two major faces, a first major face for reading out an electronic signal created in response to incident radiation and a second major face for applying a high voltage;
- and
- a high voltage biasing means connection on the second major face providing high voltage biasing to produce an electric field inside the detector,
- wherein a first of said plural detectors having said high voltage biasing means connection on the second major face providing high voltage biasing to produce an electric field inside the detector, and each other detector of said plural detectors having a high voltage biasing means connection connected with a conductor, in daisy chain, to another of said plural detectors so that the second major faces are daisy chained with conductors one second major face to another second major face.
