高速分幅相机与阳加速器的精密电流同步技术

针对在阳加速器上进行Z箍缩实验时存在的同步精度低的问题，研究了一套同步触发信号取自加速器输出电流的技术。利用加速器工作电流波形与物理实验现象间的固有延迟时间关系来判断同步的时刻，时间关联的精度可到达ns量级。为了防止加速器对测量系统的影响，根据延迟时间长短的不同情况还研究了光电隔离方式和光纤传输方式，解决了在阳加速器平台上的电磁干扰问题，实现了在阳加速器上进行可靠物理实验的精密测量工作；本触发方式配合高速分幅相机的应用，稳定而可靠地以10 ns间隔、3 ns曝光时间拍摄到了Z箍缩的发展过程。

Accurate current synchronization trigger mode for multi-framing gated camera on YANG accelerator

The current synchronization trigger mode is important for Z-pinch experiments carried out on the YANG accelerator. The technology can solve the problem of low synchronization precision. The inherent delay time between the load current waveform and the experimental phenomenon can be adopted to obtain the synchronization trigger time. The correlative time precision about ns level can be achieved in this way. The photoelectric isolator and optical fiber are used in the synchronization trigger system to eliminate the electro-magnetic interference and many accurate measurements on the YANG accelerator can be realized. The application of this trigger mode to the multi-framing gated camera synchronization trigger system has done the trick. The evolution course of Z-pinch imploding plasma has been
