Abstract (en)

The multiplier manufactured according to the invention has a very compact shape and can have the channel output electrodes arranged in any direction. The multiplying structure (94) is a ceramic block obtained by baking a stack of ceramic sheets prepared beforehand for the purpose of constituting cavities enclosed in the mass. Each cavity (21) is covered with a metallic deposition connected to a lateral contact (23) by a conductor (24) printed on the corresponding sheet beforehand. The channels can have particular geometries in order to have their output on several different surfaces (41, 46, 47) of the multiplying structure. <IMAGE>
