为了在最高的连续和脉冲磁场中进行研究，需要大型、复杂和强大的装置。本文介绍了在奈梅亨大学新建的用于连续强磁场的20兆瓦新装置。超低纹波功率转换器提供了使用电阻磁体进行高达33 T实验的能力（使用正在建设的混合磁体系统可高达40 T），对于物理，化学和生物学的基础和应用研究的前沿研究具有重要价值。通常在实验中，磁场在几分钟到一小时的时间内缓慢变化或保持恒定。冷却装置的设计允许在最大功率下不间断运行3小时，当磁场在零场和满场之间扫过时，冷却装置不会对运行造成限制。当需要更高的磁场时，可以选择持续时间为几十毫秒的脉冲磁场。
For research in the highest continuous and pulsed magnetic fields large, complex and powerful installations are needed. This paper describes the new 20 MW installation for continuous high magnetic fields that has been built at the University of Nijmegen. The ultra-low ripple power converter provides the capability to perform experiments up to 33 T with resistive magnets (up to 40 T with the hybrid magnet system under construction) and will be of great value for investigations in physics, chemistry and biology at the forefront of fundamental and applied research. Typically during experiments, the magnetic field is slowly varied or held constant for a period lasting from a few minutes to an hour. The cooling installation is designed to allow uninterrupted operation at maximum power for 3 hours, and when the magnetic field is being swept between zero and full field the cooling plant does not pose limits to the operation. When much higher fields are required, there is the option to go to pulsed magnetic fields with duration in the tens of milliseconds.
