Abstract
An ionizing radiation detector has conductive tubes arranged in parallel and containing a pressurized gas mixture, a conductive wire being pulled tight at the center of each tube and capable of being biased with respect thereto. Each tube is divided into isolated longitudinal sections. All the tube sections of a same transverse slice are electrically connected. Each group of sections of a same slice includes means for being connected to an elementary detector, wherein each slice is formed of a grid of blades.

An ionizing radiation detector comprising:
- a plurality of conductive tubes arranged in parallel containing a gas mixture, and
- a conductive wire pulled tight at the center of each of said plurality of conductive tubes and capable of being biased with respect thereto,
- wherein each of said plurality of tubes is divided into electrically isolated longitudinal sections, all the tube sections of a same transverse slice being formed of a grid of electrically connected blades and each group of sections of a same slice comprising means for being connected to a first detection circuit.
An ionizing radiation detector comprising:
- a plurality of conductive tubes arranged in parallel containing a gas mixture, and
- a conductive wire pulled tight at the center of each of said plurality of conductive tubes and capable of being biased with respect thereto,
- wherein each of said plurality of tubes is divided into electrically isolated longitudinal sections, all the tube sections of a same transverse slice being formed of a grid of electrically connected blades and each group of sections of a same slice comprising means for being connected to a first detection circuit, and wherein a first group of blades of said grid comprises a first plurality of slots which are configured to cooperate with a second plurality of slots of a second group of blades of said grid, said second group of blades being orthogonal with respect to said first group of blades.
