Abstract

Abstract

The new parametric current transformer (NPCT) in BEPC Ⅱ has heating problem in high current collide mode.To find the causes and perform stable and precise measurement, wakefield simulation and eigenmode calculation have been carried out by CST, and the steady-state temperature distribution is calculated.The cut-off frequency of ceramic gap is obtained by equivalent reflection-impedance calculation.A practical solution is put forward according to the analysis, and ideal experimental results are obtained.The experiment basically solves the heating problem, it could be a guide for current transformer (CT) improvement and applied to CT designs in the future.
