Effect of Voltage on Radiation Characteristics of Triggered Vacuum Diode

Based on the conduction mechanism of vacuum trigger diode, an experimental scheme has been designed to research on the effect of voltage parameters on radiation characteristics of vacuum trigger diode. The factors, including charging voltage and anode-cathode voltage, affecting radiation characteristics of vacuum trigger diode are analyzed. Through measure and analysis of trigger current, the reason of voltage effecting radiation is presented. With increase of charging voltage, the trigger current increases, the radiation enhances and radiation band moves up. With increase of anode-cathode voltage, more high density plasma of anode is generated by the electron bombardment anode, the radiation enhances and upper frequency limit is expanded. So it can be concluded that because of trigger electrode, radiation characteristics of vacuum diode can be controlled through voltage parameters. The vacuum diode can be controlled more flexibly and conveniently.
