    Abstract: A micro secondary electron multiplier or an array thereof employs discrete dynodes which are microstructured and applied to an insulating substrate plate. The substrate plate is provided with electrical conductor paths for the connection of the dynodes. The dynodes can be made using a technique such as X-ray depth lithography-galvanoplasty (the LIGA technique). The micro secondary electron multiplier or an array of such multipliers is extremely small and sensitive, and has a high time resolution. Furthermore there is considerable flexibility in positioning the multipliers of an array.

    Abstract: Electron multiplier element for secondary emission, consisting of a first metal plate (11) which has at least one multiplier hole (12) having one input aperture (13) and one output aperture (14), and a second metal plate (16) in parallel with the first plate (11) which has at least one auxiliary hole (17) disposed opposite the output aperture (14) of the multiplier hole (12). The second plate (16) being brought to an electric potential (V1) which is higher than the electric potential (V0) of the first plate. The apertures (13, 14) are such that the projection (18) of the output aperture (14) of the multiplier hole (12) in a plane which is parallel to the first metal plate (11) is at least partially located outside the corresponding projection (19) of the input aperture (13).

    Abstract: A photoconductive member is provided with increased sensitivity to radiation incident thereupon and with increased photo-yield in response thereto by means of a multi-layered, sandwich-type construction based upon the provision of successive layers of sensitizing material over corresponding successive layers of conducting material. The photoconductive member comprises at least two composite layers formed one above the other on an insulating substrate, each composite layer comprising a first layer of material capable of conducting charge and a second layer of material comprising polar molecules disposed upon the charge-conducting material layer in such a manner that successive layers of polar molecules are adsorbed and retained in an oriented fashion on successive layers of the charge-conducting material. In combination, the alternating layers of charge-conducting material and polar molecules increase photo-yield in response to a given quantum of incident radiation and also increase the range of wavelength of incident radiation to which the photoconductive member is responsive. The sandwich-type construction permits photoconductor sensitivity to be increased as a function of the number of layers of conducting material and polar molecules used to form the photoconductive surface. The multi-layered construction also exhibits reduced sensitivity to the degrading effects of impurities, is adapted to convenient fabrication, and exhibits extended lifetime.
