DIGITAL APPROACH TO THERMIONIC EMISSION CURRENT TO VOLTAGE CONVERSION FOR HIGH-VOLTAGE SOURCES OF ELECTRONS

The thermionic emission current is used in many vacuum devices such as evaporators, rare gas excimers, or electron beam objects for high-energy physics. stability of the a very important requirement accuracy those devices. Hence, there number control systems that use feedback signal directly proportional to order stabilize current. Most them from high-voltage anode circuit low-voltage cathode circuit. However, novel solution uses linear distribution and processing two voltage signals converting voltage. it based on old-fashioned analog technology. This paper shows conversion method with digital system. A realization multiplicative-additive algorithm presented proper work closed-loop mode confirmed.
