Title:
ION FEEDBACK ELECTRON MULTIPLIER
Document Type and Number:
Japanese Patent JPS52130276
Kind Code:
A
Abstract:
A chain of planar dynodes is divided into two groups which are spaced from and substantially parallel to each other. A cathode which is capable of emitting electrons upon ion bombardment is at one end of the dynode chain. An envelope encloses the dynodes and the cathode. Also enclosed by the envelope are a plurality of shields. Each shield is located so as to prevent gas ions, present within the envelope, from striking the dynodes, while allowing the ions to strike the cathode.
