MegaGauss facilities provide a unique environment to study materials under extreme conditions. This not only concerns samples exposed to the magnetic field in the center of a coil, but also the coil itself. The present study focuses on the deformation of copper single-turn coils (STC), specifically analyzing the impact on the material microstructure. While generating the field, STC undergo...
Single-turn coil (STC) is a kind of destructive pulsed magnet with the peak magnetic field higher than 100 T. Due to the extremely high current rising rate and peak discharge current, gas switches are often used to control the parallel discharge of multiple capacitors. However, gas switches generally have long jitter times and their triggering is difficult to maintain a high degree of...
Single-turn coil (STC) is a mainstream destructive pulsed magnet used to generate ultra-high magnetic field beyond 100 T. During the discharge process, STC is in extreme physical states with extremely high pressure and high strain rate deformation, leading to fracture and explosion of the coil. This study investigates the damage and destruction process of STC using three-dimensional finite...
Single-turn coil (STC) is a type of destructive pulsed magnet used to generate ultra-high magnetic fields ranging from 100 T to 300 T. In this study, a three-dimensional finite element simulation model of the STC is established, and the electric field distribution properties with different coil sizes and power excitations are investigated to assess the possibility of radial electric breakdown...
