Patent JP-H02171643-A (JP)
Title: Electron counter
Inventor: UDA MASAYUKI
IPC: G01N23/227
Filed: 1988-12-26
Abstract: PURPOSE:To prevent destruction of the apparatus by providing a counting means to cut off a voltage applied to an anode when a rate of counting a voltage pulse generated at an electron detecting section exceeds a specified value. CONSTITUTION:A metal case 3 is provided having a detection window section 2 below an electron detecting section 1 and an anode ring 4 and grating electrodes 5 and 6 are arranged inside. In a background mode, a voltage of an electrode 6 is fixed and the introduction of external electrons passing through the detection window 2is cut off. Then, a mode enters to count electrons alone generated like a noise within the detecting section 1. So, electrons are counted by a counting means 24 to output a rate of counting electrons from a voltage pulse outputted from an amplifier 18 of the detecting section 1. When the rate of counting exceeds a fixed value, an alarm means 30 gives an alarm. At the same time, a controlling means 26 cut off at least a power source 23 of the anode ring 4, thereby preventing a trouble possibly leading to the destruction of the apparatus.
