“…This is compared to alumina whose thermal conductivityis 0.1 cal/cm.s o C and loss tangent is also < 0.001. Thus, beryllia presents desirable properties for high power applications [1]. Given the poisoning risks of working with beryllia, we decided to verify preliminarily the agreement of the simulation with experimental results using a health risk free alumina ceramic.…”

This paper describes the development of a microwave window for high power pulsed traveling-wave tubes for radar application. Given the operational frequency band, the window dielectric materials (beryllia or alumina), and the standard waveguide (WR-90), a tridimensional frequency domain solver was used to design the window geometry. We present here the effect of the window parameters and the experimental result of a preliminary built window. The agreement between simulated and experimental results was about 97% at the beginning of the band and 92% at the end.

“…Vacuum electron devices like traveling-wave tubes (TWTs) and klystron amplifiers need hermetic sealing to keep the internal pressure in ultra-high vacuum standards [1] [3]. However, the microwave signal has to be taken in and out of the tube.…”
