Abstract
The present invention relates to a multiplier structure having a very compact shape and which can have the output electrodes of the channels arranged in any random direction. The multiplying structure (94) is a ceramic block obtained by baking a stack of ceramic sheets prepared beforehand with a view to forming cavities includes in the mass. Each cavity (21) is covered by a metal deposit connected to a lateral contact (23) by a conductor (24) printed beforehand on the corresponding sheet. The channels can have special geometries in order to have their output on several different surfaces (41, 46, 47) of the multiplying structure.
