Abstract
A transformerless Blumlein type circuit is combined with a novel clamper circuit for driving a cold cathode electron beam gun for a CO.sub.2 laser where the E-beam gun has resistance essentially infinite at the leading end of a driving pulse and has several ohms resistance at the end of the driving pulse. At the leading end of a driving pulse the voltage output of the Blumlein circuit is twice the rated load voltage since the load as infinite impedance. The clamper circuit limits the pulse voltage across the load to its rated voltage and the excess power from the Blumlein circuit over that required by the load is dissipated in the clamper circuit. The clamper circuit as variable impedance that is approximately the inverse of the load impedance during a driving pulse so that the Blumlein circuit looks into an approximately constant impedance equal to its impedance.
