【摘要】 采用PIC模拟程序对X波段50MW速调管的电子光学系统进行了初步的设计。设计的电子枪压缩比>120,阴极发射电流密度均匀,电子注轨迹层流性良好。模拟设计的电子枪区最大场强达到27.8kV/mm,属于可以承受的范围。更多还原

【Abstract】 The PIC code has been used to design the electron optics system of X-band 50MW klystron.Agun has been designed with nearly uniform beam density,the compression rate exceeding 120,the electron beam to be laminar.The maximum electro-field reach 27.8kV/mm at the electron gun area,which belong to the range that can be endured.更多还原
