Hollow Cathode for Electron Bombardment Mercury Ion Thruster Pulse Ignition Characteristics

A high voltage pulse ignitor with positive pulse output of 0.1kV-6kV has been developed. The pulse ignition voltage of the hollow cathode has been measured as a function of pulse width, pulse repeat frequencies and mercury blow rate, respectively. The comparison of the D.C. ignition voltage and puls...

Description
Summary:A high voltage pulse ignitor with positive pulse output of 0.1kV-6kV has been developed. The pulse ignition voltage of the hollow cathode has been measured as a function of pulse width, pulse repeat frequencies and mercury blow rate, respectively. The comparison of the D.C. ignition voltage and pulse ignition voltage has been made under the same operation condition of the cathode. By lowering the cathode operation temperature, two group of photograph of pulse voltage and current waveform during the cathode fire extinction have been taken. Within the test range, the pulse ignition voltage decreases while the pulse width increases and the pulse ignition voltage decreases as a straight line function while the pulse repeat frequency increases. This paper discussed the advantages of the pulse ignition. Trans. of Zhenkong Kexue Yu Jishu (China) v4 n6 p387-398 1984.
