摘要
对同轴Ｓｕｐｅｒ－Ｒｅｌｔｒｏｎ进行了物理分析和数值模拟，在调制腔电压１２５ｋＶ、加速间隙电压６００ｋＶ和电流１５ｋＡ时，在Ｃ波段获得了峰值功率约２．５ＧＷ和效率约２５％的结果，都较以前大大提高。计算表明频率与箔的高度成反比。在电流达到空间电荷极限以前，微波输出功率和电流的平方成正比。
A new coaxialstructure SuperReltron was explored to develop a lowimpedance high power microwave tube. This source will have a power output of about 2.5GW with 25% efficiency at 52GHz, input modulate voltage is 125kV and postaccelerating voltage is 600kV. Numerical simulations show that the frequency is approximately inversely proportional to the length of screen, and the scaling of output power is proportional to I2, when the current is less than the space charge-limit .
