Abstract:

The purpose of this program is to investigate the feasibility of fabricating thin-wafer channel multiplier arrays by a novel approach and to produce experimental operational models thereof suitable for evaluating the performance characteristics and potential capabilities of such devices. The approach involves using advanced thin-film technology to prepare a base film with a dense array of submicron-size holes, followed by deposition of dynode material on the base to form the individual channel walls. A conductive film on each channel wafer face will permit application of the requisite operational potential. The dense wafers are to be constructed entirely of refractory materials in a vacuum environment and, therefore, should not be a source of contamination of their working environment when in use. Thus, when such an array is interposed between a photo-emitter and a phosphor screen it should provide a relatively stable, high-resolution, amplified electron-image for direct viewing or other image conversion functions.
