Hundreds megawatt-level pulse transmission waveguide vacuum port using series inductive post-wall

ABSTRACT A simple waveguide vacuum port for hundreds MW pulse transmission at S‐band is proposed. It uses the series inductive post‐wall to improve the characteristics of the RF leakage attenuation and maximize the unit area of the vacuum port related with effective pumping speed. This type of vacuu...

Summary:ABSTRACT A simple waveguide vacuum port for hundreds MW pulse transmission at S‐band is proposed. It uses the series inductive post‐wall to improve the characteristics of the RF leakage attenuation and maximize the unit area of the vacuum port related with effective pumping speed. This type of vacuum port significantly increases RF leakage attenuation above −50 dB without RF electrical breakdown phenomena and provides simple structure to enhance the conductance Cwg−p of the waveguide vacuum port found to be around 0.7Cwg for above −50 dB RF leakage attenuation. © 2014 Wiley Periodicals, Inc.
