Yoshimitsu Kohama, Koichi Kindo

摘要:

我们描述了一个简单的,紧凑的,具有成本效益的反馈系统,产生平顶场分布在脉冲磁场的建设。该系统被设计用于与典型的电容器组驱动的脉冲磁体结合使用,并使用60 T脉冲磁体进行了测试。利用所开发的反馈控制器,我们已经证明了平顶磁场高达60.64 T,具有+-0.005 T的出色的场稳定性。结果表明,平顶脉冲磁场具有磁场稳定性高、场强可达等特点。这些特征使得该系统可用于通过信号平均来提高数据的分辨率。

英文摘要:

We describe the construction of a simple, compact, and cost-effective feedback system that produces flat-top field profiles in pulsed magnetic fields. This system is designed for use in conjunction with a typical capacitor-bank driven pulsed magnet, and was tested using a 60-T pulsed magnet. With the developed feedback controller, we have demonstrated flat-top magnetic fields as high as 60.64 T with an excellent field stability of +-0.005 T. The result indicates that the flat-top pulsed magnetic field produced features high field stability and an accessible field strength. These features make this system useful for improving the resolution of data with signal averaging.
