Abstract

Abstract:

According to the theory of ceramic window design, using electromagnetic field simulator, CST, and finite element method analysis software, ANSYS, the electromagnetic and thermal performances of LHCD new ceramic window have been calculated and simulated. BeO is used as windows body material for its high conductivity. Within the bandwidth of more than 300MHz, the stationary wave ratio is below 1.1, and the maximum temperature rising is 11.7?C on the center of the ceramic window.

Key words: LHCD, Ceramic window, Thermal stress
