Klystrode experimental results

A 500-kW peak power, 50-kW average, 425-MHz Klystrode has been designed and built. The high-power Klystrode design evolved from earlier work on a new line of UHF TV Klystrodes. Experimental testing has proceeded in three phases. The initial testing was done on a beam simulation device to determine the characteristics of the gridded gun. The second phase consisted of low-duty-cycle, full-voltage and current RF testing on the Klystrode built for the contract. The third phase will continue the testing at the full specification conditions. The basic operating principles are summarized, and test results are presented.<>
