Device for linear detection of radiation

Device for detection of a radiation beam, which comprises:

• at least one thin plate of a dense scintillating material,
• at least one group of fluorescent optical fibers, which can be excited by the visible light emitted by the scintillating material under the impact of radiation, these fibers having portions which are parallel, adjacent and attached to one of the two faces of the plate, and
• means for displacement of said plate relative to the incident beam, this plate having a sufficient depth to stop the major part of the radiation which has penetrated the plate through its edge,
• the device thus making possible locating, along the edge of the plate, the impact of the particles of the incident radiation and forming a bidimensional detector due to the relative displacement.

• for each fiber, a means for detection of the light of fluorescence produced and guided by this fiber when it is excited, and
• electronic means for processing signals provided by the detection means,
• the device thus making possible locating, along the edge of the plate, the impact of the particles of the incident radiation.
