Abstract: An electron tube device comprising an electron tube having a line cathode, and an electric power source for supplying power pulses to the line cathode. The electron tube device comprises determination means for determining, during a power pulse, the value of a physical quantity which depends on the temperature of the line cathode, comparison means for comparing the value with a reference value and for supplying a control signal, and termination means to end the power pulse in dependence on the control signal. Consequently, the temperature of the line cathode is more stable.

Abstract: A system for stabilizing the cathode emissions of an in-line gun cathode ray tube includes subsystems functionally identical to one another linked to each of the cathodes of an in-line gun cathode ray tube. During the time that the CRT beam is retracing vertically, each subsystem imposes a fixed, predetermined voltage on a cathode in the cathode ray tube, samples the current flowing to the cathode, compares the sampled current to a predetermined, desired reference current for the cathode, develops a differential signal representing the difference, if any, between the sampled current and the reference current, and then drives the current flowing to the cathode from its actual value to its predetermined, reference value so as to maintain a predetermined, desired ratio of the currents flowing to each of the cathodes.
