ns-200 accelerator beam pulsed technical research and simulate calculate of beam transfer

在ns-200中子发生器上开展了束流脉冲化技术研究工作,采用正弦波速调管聚束方法设计了束流脉冲化系统,研制了高频电源系统、脉冲测量系统和远程自动控制系统。运用LEADS软件,进行了束流传输的模拟计算,并显示了束流传输包络曲线。整机安装调试获得了半高宽小于3.5ns、峰值电流大于1mA的聚束脉冲,束流稳定,各项指标达到技术要求。目前,已长期投入脉冲运行,完成了多个物理实验。

In order to satisfy the equipment of physical experiment , it developed beam pulse technology research on ns-200 accelerator. It uses sine-wave beam adjustment pipe focused beam match design research beam pulse system, high frequency power supply system, pulse measure system and distance autocontrol system. Use the LEADS software to simulate the calculation of beam transfer, and show the envelope curve of beam transfer. The whole machine gained focused beam pulse that the half width is less than 3.5ms and peak value is more than lmA, The beam pulse is stable and each parameter has reached the technical requirement. Now it has been used in experiments. pulse for a long time and has achieved lots of physical experiments.
