Abstract:
A method for leaktight sealing a matrix radiation detector of large size having a plurality of elementary detectors which are formed on a central zone of an insulating substrate, said detectors being covered by a layer of scintillating substance that is in turn covered by a radiation window made of a material that permits radiation to be detected to pass there through to impinge on the layer of scintillating substance beneath the radiation window while being impervious to atmospheric moisture, said method comprising:connecting the elementary detectors to contact pads provided in separate peripheral connection zones outside of said central zone on different peripheral portions of said insulating substrate; connecting end portions of flexible multiconductor cables to said contact pads; and depositing a sealing layer of material impermeable to atmospheric moisture in a single operation in contact with the contact pads and the end portions of the flexible multiconductor cables at the peripheral connection zones and the periphery of said layer of scintillating substance without covering a central portion of the radiation window so as to seal the contact pads and the end portions of the flexible multiconductor cables together with the periphery of said layer of scintillating substance while leaving another portion of each of the flexible cables extending from the end portions and at least the central portion of the radiation-window free of the deposited layer of material impermeable to atmospheric moisture.
