Abstract

In manufacture of a channel intensifier device having input and output electrode layers on its major faces, and elongated resistive and secondary-emissive channels extending therebetween, a number of tubes are essembled into a bundle and sealed together, whilst being forced to merge together to the extent of filling the interstices therebetween, to form a rigid channelled block. The intersifier device may be used in light or X-ray image intensifier of the kind described in Specifications 1,064,073 and 1,064,074. The tubes may be lengths of hollow drawn glass tubing or may have metal cores which are removed after formation of the block. In the latter case, the tubes may be obtained by drawing glass tubing over a metal wire, by drawing glass tubing which already contains a metal core, or by pulling a preformed wire through a bath of molten tube material. The tubes so formed, with or without cores, may be assembled into bundles by winding single or multiple drawn tubing into a hank and cutting the hank into lengths. The bundles may be packed into tubular glass formers which are heated to softening point and evacuated to seal the tubes together under pressure, hollow tubes being air-filled to prevent collapse. Alternatively the bundles may be packed in carbon jigs, so that upon heating the tubes expand more than the carbon and are thus compressed together. The tubes may be coated with a low-melting point glaze to enable sealing to be effected at a lower temperature. After sealing, the bundles may be sliced to form the final matrix or may be drawn down to form multiple fibres which are assembled together to form the final matrix. In the latter case, the multiple fibres should be of regular cross-section, e.g. square, triangular, diamond or hexagonal, to permit close packing in the final bundle. The metal core material, if used, may be In, Pb, Sn, Zn, Al, Cu, W or Au and may be melted out or removed by chemical etching. The tubes may be of lime soda or borosilicate glass, and may have slightly conductive layers on their inner surfaces, or may have a bulk resistivity of 109-1011 ohms/cm. Specific dimensions are given.
