摘要:

This paper describes an instrument based on Busch’s method of determininge/mfor electrons. A square-wave deflection voltage is used for deflecting an electron beam. With this instrument, one can more easily and more accurately determinee/mfor the electron. A comparison is made experimentally and theoretically among several ways of deflecting an electron beam.
