Filed: 1970-11-27
Abstract: 1333417 Image intensifier pick up tubes MULLARD Ltd 21 Oct 1971 [27 Nov 1970] 56478/70 Heading H1D A pick up tube (e.g. for television) comprises an electron image intensifier stage employing a channel plate, a channelled extension on the channel plate comprising insulative or resistive layer D, and separate output signal electrode E3, a storage target film T closing the output end of each channel, and an electron gun for scanning the face of the target remote from the channel plate. The extension may comprise more than one resistive or insulating layer D laid on the output electrode of the channel plate a separate electrode layer. The integral arrangement reduces resolution loss due to electron transfer between channels. If the first layer of the extension is resistive, it may have a minimum resistivity comparable to a channel plate section of equal thickness, or a higher value. The target may cover the channel ends without covering the remainder of the face, and is preferably of secondary emission > 1. Channel diameters of 10 to 20 Á or smaller are mentioned. In Figs. 1 and 2 (not shown) channel plate I may be remote from photo cathode P as an alternative to a "proximity', configuration Fig. 2 showing a modified Catchpole arrangement not forming part of the present invention. Positive charge image pattern is formed on target T with a positive bias between electrode E2 and cathode K of gun G, secondary emission from T to mesh M possibly being utilized, mesh M being 1 to 2 mms. from the target. Fibre optics may be incorporated as in Fig. 1 and secondary electrons may be collected by electrode E2 and possibly mesh M, latter being connected to the gun final anode or a variable HT unit. In Fig. 3 source Bt improves secondary electron collection, p.d. values being instanced. Target materials may be as in image orthicons, e.g. glasses or magnesium oxide, target conductivities or 2 Î 10<SP>11</SP> #/cm. and thickness 5 Á. MgO targets may be formed by evaporating then oxidised by heating, the granular structure having lower lateral than normal conductivity. Layer D may be silicon monoxide formed by evaporation on to E2. The target may be evaporated on to a support film of nitrocellulose floated on the plate then baked away, which may simultaneously oxidize the Mg. Electrode E2 may extend into the channels to one or a few diameters depth to form focusing lenses, the channels may be inclined to combat ion feedback. The Fig. 3 arrangement is preferred to that of Fig. 2 since D.C. channel plate noise current by-passes load R and E3 and E2 voltages may be varied. Photocathode P may be coupled to an X-ray sensitive input phosphor, and system A may demagnify for small channel plates. Variation of Bt and Bk allow secondary emission to be greater or smaller than unity. Low light level TV, with military applications is exemplified. Reference is made to Specifications 1,064,072; 1,064,073; 1,064,074; 1,064,075, 1,064,076; 1,090,406; 1,154,515.
