ABSTRACT:
An electron multiplier includes an improved resistor assembly for applying relevant voltages to respective dynodes. Resistor patterns are printed on one surface of an insulation substrate. Each resistor pattern is connected to one end of one of a plurality of conductor patterns which are also printed on the same surface of the insulation substrate, so that each resistor pattern is sandwiched between adjacent conductor patterns to provide a predetermined resistance therebetween. The other end of each conductor pattern extends to a corresponding insertion hole formed on the insulation substrate. One end of a conductor element, which may be a lead, wire, or other wire shaped conductor, is inserted into the corresponding insertion hole and electrically connected to its corresponding conductor pattern. At least the area around where the conductor pattern is connected to the conductor element and also areas around resistor patterns are covered with an insulating seal material. The other end of each conductor element is left exposed without being covered with the seal material and connected to a corresponding dynode.
