我们报道了一种水平场、30特斯拉磁体系统的设计、建造和运行情况，该系统具有一个为同步辐射X射线粉末衍射优化的锥形孔。该磁体在样品下游提供±31°的光学通路，这使得能够测量足够多的德拜环以进行精确的晶体结构分析。结合一个290千焦的发生器，在磁体中产生了时长为60毫秒的磁场脉冲，其上升时间为4.1毫秒，在30特斯拉时的重复频率为每小时6个脉冲。线圈安装在液氮浴内。一个液氦流动低温恒温器伸入线圈内，可使样品温度处于5到250开尔文之间。该装置在欧洲同步辐射设施的ID20和ID06光束线上得到了应用。
We report on the design, construction, and operation of a horizontal field, 30 T magnet system with a conical bore optimized for synchrotron x-ray powder diffraction. The magnet offers ±31° optical access downstream of the sample, which allows to measure a sufficiently large number of Debye rings for an accurate crystal structure analysis. Combined with a 290 kJ generator, magnetic field pulses of 60 ms length were generated in the magnet, with a rise time of 4.1 ms and a repetition rate of 6 pulses/h at 30 T. The coil is mounted inside a liquid nitrogen bath. A liquid helium flow cryostat reaches into the coil and allows sample temperature between 5 and 250 K. The setup was used on the European Synchrotron Radiation Facility beamlines ID20 and ID06.
