在装置“S-300”上,通过测量真空磁绝缘传输线中电极间电子流轫致辐射和负载上的电流、电压等参数,研究了磁绝缘传输线中的电流损失特性。实验中使用了阻抗特性不同的3种负载,结果表明,磁绝缘传输线中的电流损失特性显著地取决于负载。当负载为丝阵靶时,电流损失出现在丝阵等离子体最大箍缩时刻,且其值不超过负载总电流的5%。
On the device “S-300”, the current loss characteristics in the magnetically insulated transmission line were investigated by measuring the electron-beam emission and the current and voltage on the vacuum magnetic insulated transmission line. Three kinds of loads with different impedance characteristics were used in the experiment. The results show that the current loss characteristic in the magnetically insulated transmission line significantly depends on the load. When the load is a filament array target, the current loss occurs at the maximum pinch time of the filament plasma and its value does not exceed 5% of the total load current.
