The invention discloses a structure and an
assembly method of an
electron multiplier, An
electron multiplier is composed of a low substrate, an upper substrate
motherboard, an upper substrate assistedplate, a dozen
electrode assembly and a collector
assembly; A plane-type
voltage dividing
resistor and a flat-type transition
electrode are arranged on the upper surface of the upper substrate main board, A main board of that upper substrate is provide with a dozen mounting hole corresponding to an
electrical connection hole of the dozen assembly, A surface-type transition
electrode is electrically connected with that mounting hole of the dozen electrode, A planar
voltage dividing
resistor and a planar transition electrode are partially overlapped and electrically connected, Then, the dozen electrode assembly and the collector assembly are fixed between the lower substrate and the upper substrate main board, and the upper substrate auxiliary board is fixed on the upper end of the upper substrate main board, so that the space between the upper substrate auxiliary board and the upper substrate main board is reduced, the
resistor film layer and the transition electrode film layer are partially overlapped, and the
electrical connection is very reliable; The
voltage dividing resistor, the transition electrode and the upper substrate main board are integrated into one body, and each voltage dividing resistor need not be soldered one by one, and the structure is compact, so that the assembly link of the
soldering resistor is reduced.
