-
摘要: 提出了脉冲磁场中波导管涡流影响的数值模拟方案，编制了EDDYC程序，研究了波导管电导率、管径、壁厚和激励电流角频率等对波导管涡流的影响，对将在二极管-速调管实验中使用的不锈钢（1Cr18Ni9Ti）波导管的涡流影响进行了模拟。Abstract: In this paper we present a numerical simulation programme about eddy current influences of waveguide pipe in pulsed magnetic field. We study effects of waveguide conductivity s , pipe radius R, wall thickness D R and excitation current angular frequency w on eddy current. Finally, we calculate influences of eddy current of stainless steel (1Cr18Ni9Ti) pipe which will be used in diode-relativistic klystron experiment.
