ABSTRACT:
A mesh electrode 9 is provided over an incident opening 7a of the electron multiplication portion 6. In the electron multiplication portion 6, a dynode group Dy is located downstream of a first dynode Dy1 for multiplying electrons supplied from the first dynode Dy1. The dynode group Dy is provided in the vicinity of the curvature center of the first dynode Dy1. A plate electrode 10 and a mesh electrode 9 are supplied with a potential intermediate between the potentials applied to the first dynode Dy1 and applied to the dynode group Dy. Accordingly, the electric field formed due to the potential difference between the first dynode Dy1 and the dynode group Dy is surrounded by the intermediate potentials. The electric field is therefore uniformly distributed over the region from the vicinity of the first dynode Dy1 toward the dynode group Dy.
