Arrangement for regulating the operating parameters of an electron beam generator

摘要

An arrangement for regulating the operating parameters of an electron beam generator in which the main cathode is indirectly heated by a directly-heated auxiliary cathode. A regulating circuit connected to the auxiliary cathode has three individual regulators connected in tandem for regulating the auxiliary cathode. Three separate signals corresponding to the accelerating voltage of the auxiliary cathode, the emission current of the auxiliary cathode, and the emission current of the main cathode are applied respectively to the inputs of the three individual regulators in feedback arrangement.
