Abstract
An ionizing radiation detector comprising a plurality of conductive tubes arranged in parallel fashion containing a gas mixture under pressure, a conductive wire being tensed at the center of each tube and adapted to being polarized with respect thereto, and comprising first and second tight enclosures each having a wall provided with openings in which are tightly inserted the first and second ends of each tube, the ends of each tube being open.
Claims8
An ionizing radiation detector comprising a plurality of conductive tubes (18) arranged in parallel fashion containing a gas mixture under pressure, a conductive wire (26) being tensed at the center of each tube and adapted to being polarized with respect thereto, the ionizing radiation being directed approximately orthogonally to the direction of the tubes, comprising:
- first and second tight enclosures (20, 22) each having a wall provided with openings in which are tightly inserted the first and second ends of each tube (18), the ends of each tube being open.
The detector of any of the foregoing claims, wherein the ends of the tubes (18) have a predetermined diameter lower than the diameter of the tube bulk, the openings of the walls (20, 22) in which are inserted the ends of two adjacent tubes (18) being distant by a space equal to the difference existing between the diameter of the end of the tubes and the diameter of the tube bulk, said ends of the tube being welded to said openings of the walls.
A method for manufacturing an ionizing radiation detector comprising the steps of:
- inserting the first and second ends of a plurality of conductive tubes (18) into openings made in a metallic wall of a first (20) and of a second (22) tight enclosures so that the tubes are arranged in parallel fashion;
- attaching simultaneously or one after the other by welding each end of each tube (18) in the opening of which said end is inserted, so that the inside of the tubes (18) and the inside of the tight enclosures (20, 22) are tightly connected;
- and
- filling the tight enclosures (20, 22) and the tubes (18) with a predetermined gas mixture at a predetermined pressure.
