    以0.3 THz回旋管为研究对象，对 TE06模回旋管腔体进行理论分析和起振电流的计算，以避免模式竞争的出现。对选取的电参数进行粒子模拟仿真，在10 kV和300 mA条件下得到 TE06模输出、平均输出功率为152 W及输出频率为299.5 GHz的模拟结果，并对不同磁场和不同电流情况下输出功率进行了分析，为太赫兹回旋管的研制提供参考。

    Terahertz(THz) gyrotron is one of the specially developed high power THz radiation resources, and have important applications in biology, physic and faraway exploration. The cavity structure and physical mechanism of a 0.3 THz low voltage gyrotron for TE06 mode is analyzed. The start-oscillation current is calculated to suppress mode competition. The beam-wave interaction parameters are chosen in Particle-In-Cell(PIC) simulation. TE06 mode appearance, the output power of 152 W and output frequency of 299.5 GHz are obtained by beam-wave interaction simulation at 10 kV and 300 mA. Finally, output power in different magnetic fields and work currents is analyzed, which can provide important reference for the development of terahertz gyrotron.
