Abstract
A method and circuit for preventing excessive CRT X-ray production by continually measuring operating parameters of the CRT that are correlated with X-ray production during this operation. The measured parameters are continually compared with predetermined limit values, and various CRT operation controls are adjusted in response to the comparison to maintain the measured parameter values below the predetermined limit values.
