The Dresden High Magnetic Field Laboratory (HLD) is a pulsed-field user facility, which provides external and in-house researchers with the possibility to perform a broad range of experiments in pulsed magnetic fields [1]. Being a member of the European Magnetic Field Laboratory (EMFL), HLD offers access and supports more than 100 scientific projects annually. At the HLD, a diverse set of...

The flat-top pulsed magnetic field can meet the requirements of many cutting-edge basic scientific researches on higher magnetic field, longer duration, and higher stability. In this study, a magnet is developed to generate 60 T pulsed magnetic field with 100 ms flat-top. Compared to conventional pulsed magnets, it has a larger internal hole diameter of 38 mm. In the design, a power-magnet...

Pulsed high-field magnets serve as a crucial tool for the frontiers of fundamental researches. With the development of internal reinforcing techniques, magnetic fields up to approximately 65 T can now be generated with a simple coil. However, as the target magnetic field increases, the use of multiple coils becomes necessary to manage internal stress. Magnetic systems exceeding 80 T typically...

Split pulsed magnets are widely employed in high temperature superconducting (HTS) motor armature winding as magnetizing coils to implement in-situ pulsed field magnetization (PFM) for HTS field pole magnets. We have designed and developed a split pulsed magnet, that balances a peak central magnetic field of nearly 7 T and a rise time of 24 ms, making it particularly suitable for PFM of HTS...

The flat-top pulsed magnet field (FTPMF) can achieve the fields above 40 T with long duration, which enables the development of the terahertz gyrotron of 1THz with the operation width longer than 1 ms. The performance of the gyrotron is significantly influenced by the stability of FTPMF. Using a small compensation coil built into the bore of the magnet is a practical method to achieve the...

Quasi-force-free magnets, with their small volume and low inductance characteristics, are considered a promising option for the magnetic system in THz gyrotrons. However, the current quasi-force-free magnets suffer from complex structures that are difficult to fabricate. Moreover, due to the inherent instability of their structure, a dielectric with a sufficiently high Young's modulus needs to...
