Multi-channel radiation detector array

Claim 1

A radiation detector comprising: a pair of support members set apart in a direction perpendicular to an incident radiation, each support member having a face facing the other support member and a plurality of grooves cut in the face, said grooves being juxtaposed at predetermined intervals along an arc, the center of which is a source of said radiation, extending along the incident rays of said radiation and aligned to the grooves of the other support member; and a plurality of detector units supported by the support members and juxtaposed along said arc, each of said detector units comprising: a base plate having a notch in a side thereof facing the radiation source; a plate-like detector element, fitted and secured in the notch of said base plate, for detecting the incident radiation rays, two major surfaces of said detector element being parallel with those of the base plate which is thinner than the detector element; two electrode layers formed on and electrically connected to the two major surfaces of said detector element, respectively; a retaining plate holding, by using an adhesive material, the detector element at one of the major surfaces thereof, the ends of said retaining plate being engaged in one of the grooves cut in one support member and in that groove cut in the other support member which is opposite to said groove; and two lead electrodes formed on and electrically connected to the major surfaces of said base plate, respectively.
