Experiments on the high efficiency operation of the modified peniotron oscillator

Invention and developments of peniotron and ledatron

“…We carried experiments to confirm this feature by using the test tube with a TEII rectangular waveguide cavity at 10 GHz. Then, we obtained an elctronic efficiency of 62%, corresponding to a rotational energy conversion efficiency of 77% [10]. This value is somewhat lower than expected one, it is probably due to a poor quality of the used electron beam.…”

Experiments on highly efficient operation of the auto-resonant peniotron oscillator

“…To form the cycloiding hollow electron beam necessary for peniotron operation, we used a DC magnetic cusp field. Details of the axes alignment technique and the formation of a cycloliding electron beam are described in our previous papers (Yokoo et al 1988(Yokoo et al , 1989.…”
