High efficiency and high homogeneity large-area gas-filled radiation detector
View Patent ↗In a preferred embodiment, a radiation detector, including: one or more anode wires disposed within a body of the radiation detector, connections to and suspension of the one or more anode wires being made externally of active volume of said radiation detector.
1. A radiation detector, comprising:
(a) a detector body that has spaces on the opposite side walls for mounting wire supporting elements;
(b) an anode arrangement including one or more anode wires and means for supporting them;
(c) a window made from a thin metallic foil or metallo-plastic composition and hermetically covering the open plane of said detector body; and
(d) said wire supporting elements and cable connection(s) from said one or more anode wires to readout electronics together not protruding beyond said side walls, inside and outside.
2. A radiation detector, as defined in claim 1 , wherein: said radiation detector is gas-filled.
3. A radiation detector, as defined in claim 1 , wherein: said wire supporting elements have metal pads on both sides and a metallized hole between said metal pads.
4. A radiation detector, as defined in claim 3 , wherein: said anode wires are installed through said holes and permanently attached to said metal pads using either a soldering technique or an electrically conductive adhesive.
5. A radiation detector, as defined in claim 1 , wherein body of said radiation detector is made from metal or metallized plastic, thickness of the walls is in a range of 2-5 mm.
6. A radiation detector, as defined in claim 1 , wherein: depth of said spaces is such that there is a clearance of from about 1 mm to about 2 mm between a top surface of said wire supporting elements are an outer surface of said side wall of said radiation detector.
7. A radiation detector, as defined in claim 1 , wherein: an internal active volume of said radiation detector may comprise two or more sections, electrically an optically separated one from another by internal dividers.
8. A radiation detector having side walls, comprising: one or more anode wires disposed within a body of said radiation detector, connections to and suspension of said one or more anode wires being made externally of active volume of said radiation detector, said anode wires and connections not protruding beyond said side walls, inside and outside.
