More Information
Summary:Bidimensional detector of ionizing radiation and manufacturing process for the detector. The detector includes a block created from a material which releases secondary particles by interaction with incident ionizing radiation with an energy level greater than or equal to 100 keV. The thickness of the block is at least equal to one-tenth of the mean free path traveled by the incident ionizing radiation particles in the material. Parallel slits run through the block and the slits are filled with a fluid configured to interact with the secondary particles to produce other particles representing the radiation. The block, and then the slits, are formed, for example, by waterjet cutting, electrical discharge machining, or roll-out stretch wire. The bidimensional detector can be used, for example, for radiographic purposes.
