Abstract
PCT No. PCT/FR 78/00046 Sec. 371 Date Aug. 2, 1979 Sec. 102(e) Date Aug. 2, 1979 PCT Filed Dec. 7, 1978 PCT Pub. No. W079/00353 PCT Pub. Date June 28, 1979 A device for detecting and localizing soft gamma and X radiations, comprising an enclosure 10 provided with a window 11 opaque to light and transparent to incident radiations, occupied by a noble gas and provided with electrodes for causing the electrons to drift towards a secondary photon creation space. In said space there reigns an electric field having sufficient value to cause the formation of secondary photons by excitation then de-excitation of the atoms of the noble gas. The secondary photons pass through a transparent window 12 and are converted into photons in the close UV or visible spectrum. The scintillations are localized by PM tubes 23 and 24.
