Filed: 1981-06-16
Abstract: PURPOSE:To make constant the brightness of irradiation electron beam, by converting voltage or signal obtained from a sample into voltage to compare with reference voltage to impress the bias voltage corresponding to the difference. CONSTITUTION:Sample current is detected by a Faraday cup 10' on a sample base being converted 16 into voltage to compare 17 with the reference voltage 8. When the both a bias resistor 20 as the meter for voltage potential and a servo motor rotating by rotation angles correlated with difference input 17 provided on the side of a control circuit 19 are coupled by a shaft, the bias resistance is varied with the difference input 17 for the automatic control of bias voltage.
