| Description |
The PASOTRON mainly consists of plasma cathode electron gun (PCE-gun), periodic slow
wave structure and radiating antenna [1] . An X-Band PASOTRON is being developed, in
which, a sinusoidal rippled wall waveguide is chosen as slow wave structure (SWS). The
reasons for this choice are that it has relatively simple structure, provides fairly effective
conversion of electron-beam energy into radiation, and can be easily filled with plasma.
We present an experimental and simulation study of a slow wave structure which consists
of a cylindrical waveguide with sinusoidal varying radius. A similar version of this structure
was used in numerous X-band relativistic high-power backward wave oscillator
experiments [2], however, until now there has not been a systematic analysis of its
electromagnetic properties [3]. The purpose of this study is to experimentally determine the dispersion relation of the structure and compare it with the simulation results. The resonant
method [4] we use is simple and requires less time and effort as compared to non-resonant
methods [5] where we have to move a bead through the structure which makes process
complicated. In the technique we use , an advantage of our structure being a resonant structure has been taken.
