5 T pulsed magnetic field generator of the Flash-Ⅱ accelerator

For the requirements of thermodynamic effect research, a high magnetic field system was designed. The high magnetic field system is consisted of four components: capacitor bank, semiconducting output switch, magnetic coil and high voltage power supply. The designed max magnetic field is 5 T and the magnetic lens ratio could be adjusted by changing the distance between magnetic coil and diode. Key parameters of the magnetic field are investigated by theoretical analysis and numerical simulation. Based on the theoretical analysis and numerical results, a high magnetic field generator has been manufactured. The experiments with the generator show that when the capacitor bank is charged to 20 kV, the max magnetic induction intensity at the coil center is 5.3 T.
