Abstract

The design of 3.7GHz ceramic window is needed in the Lower Hybrid Current Drive (LHCD) system of Experimental Advanced Superconducting Tokamak (EAST). The material of ceramic disk chooses BeO which owns low dielectric constant, low loss tangent and high thermal conductivity. RF results obtained from the analysis of HFSS software show that the voltage standing wave ratio (VSWR) is less than 1.05 during the bandwidth from 3.5GHz to 3.9GHz. Thermal analysis is analyzed by ANSYS finite element software. When the water flow rate is 0.36t/h, the maximum temperature differential on the ceramic disk is 26 and the thermal stress is in a safe range.
