Abstract: A miniature electron multiplier having a pair of complementary dynode support elements formed of ceramic material, each of the elements having a plurality of longitudinally spaced-apart projections extending transversely outwardly from a side thereof and mutually defining outwardly facing recesses therebetween. The elements are disposed with their sides in spaced, parallel facing relationship with the projections of one element located generally midway between the projections of the other element and respectively extending toward the recesses of the other element but having their outer ends spaced from the side thereof so as to define a generally serpentine channel. A plurality of dynode elements formed of relatively thin sheet metal are respectively seated in the recesses and brazed to the walls thereof. Top and bottom plate elements formed of ceramic material secure the support elements in assembled relation and close the channel. The dynode elements have integral leads which extend outwardly between the respective support element and plate element to the exterior of the assembly where they may be attached to a voltage divider resistance printed upon the outer surface of one of the cover plates.
