Abstract
There is disclosed an electron shower apparatus which eliminates the adverse effect of a magnetic field on electrons and which provides electrons in sufficient quantity when primary electrons having low energy are employed. In the apparatus, the magnetic field generated by a filament current is decreased or eliminated by pulsing the filament current or by passing a current opposite in direction to the filament current in the vicinity of the filament current.
