Abstract: Disclosed is a header for a radiation detector assembly provided for mounting a detector head into an enclosure formed by the header and a detector can to form the radiation detector assembly. The detector head includes a semiconductor radiation detector arranged on a first side of a substrate and a thermoelectric cooler, TEC, arranged on a second side of the substrate, the header including: a base plate having a first side for mounting the TEC and a second side with an attachment mechanism for attaching the radiation detector assembly to a radiation-detecting appliance; contact pins that provide electrical coupling through the base plate protruding from the first side of the base plate to substantially define a rim for accommodating the TEC within the rim; and a draining outlet with an opening through the base plate between its first and second sides transferring a gas to and/or from the enclosure.

Abstract: A semiconductor radiation detector includes a bulk layer of semiconductor material. On a first side of said bulk layer is an arrangement of field electrodes and a collection electrode for collecting radiation-induced signal charges from said bulk layer. A radiation shield exists on a second side of said bulk layer, opposite to said first side, which radiation shield selectively overlaps the location of said collection electrode.

Abstract: A semiconductor radiation detector crystal is patterned by using a Q-switched laser to selectively remove material from a surface of said semiconductor radiation detector crystal, thus producing a groove in said surface that penetrates deeper than the thickness of a diffused layer on said surface.

Abstract: A gas tight radiation window membrane comprises a layered diffusion barrier with a reactive metal layer (201) covered on both sides by cover layers (202, 203). An originally continuous carrier layer (101) can be made a mesh that has openings coincident with openings of a reinforcement grid (105), while the gas tight diffusion barrier (107, 507) spans as a continuous film over said openings in said mesh.

Abstract: A collimator for collimating X-rays in an X-ray spectrometric measuring apparatus comprises a body of a microchannel plate (203, 205, 701, 702, 703, 704, 705, 711, 712, 713, 714, 715, 801, 901, 1003). Most advantageously the channel walls of the microchannel plate are plated with a thin coating (310) of a heavy metal.
