Bulk Superconductors for Benchtop NMR

块体高温超导体(HTS)可以作为伪永磁体，具有相当好的俘获磁场性能。该项目旨在开发一种用于台式核磁共振光谱仪的高性价比块状高温超导磁体系统，使核磁共振硬件更实惠、更容易获得。这带来了极大地加速化学和生物创新的潜力。就像永磁体材料一样，块状高温超导需要被磁化，或者说“带电”。与永久磁铁不同，充电系统必须在设备中，因为磁场在升温时会丢失。这是实现商业上可行的块状高温超导磁体的主要挑战之一。此外，了解充电过程并绘制块体内的磁场图对于实现利用块体高温超导的产品至关重要。该项目的主要重点将是优化脉冲充电技术，以创造出适合于核磁共振光谱的块状高温超导磁体。

Bulk high temperature superconductors (HTS) can be used as pseudo-permanent magnets with considerably better trapped magnetic field performance. This project aims to develop a cost-effective bulk HTS based magnet system for benchtop NMR spectrometers, making NMR hardware much more affordable and accessible. This carries the potential to greatly accelerate innovation in chemistry and biology.Like permanent magnet materials, bulk HTS need to be magnetised, or 'charged'. Unlike permanent magnets the charging system must be in the device, as magnetic field is lost on warming. This is one of the primary challenges to realising a commercially viable bulk HTS magnet. In addition, understanding the charging process and mapping the magnetic field attained within the bulk is essential to realising products utilising bulk HTS. The primary focus of the project will be on optimising the pulse charging technique to create a bulk HTS magnet suitable for NMR spectroscopy.
