ABSTRACT:
A venetian blind dynode5A and metal channel dynodes5B of a dynode unit5are fitted along with insulating spacers (insulating plates)11on columns9erected on a stem plate3that makes up a vacuum container, and since in this state, venetian blind dynode5A, metal channel dynodes5B, and insulating spacers (insulating plates)11are supported integrally and firmly by columns9, venetian blind dynode5A, metal channel dynodes5B, and insulating spacers (insulating plates)11will not undergo inadvertent lateral deviation due to vibration or impact and dynode unit5exhibits an excellent anti-vibration effect.
