The experimental research on explosively high magnetic field generator

Abstract

The cylindrical isentropic compression by high magnetic field pressure is very useful in high energy density physics. Some primary experimental works on the explosively magnetic flux compression generator had been carried out since 2011 at Institute of Fluid Physics, Chinese Academy of Engineering Physics (IFP, CAEP). A traditional configuration of explosively driven flux generator had been designed and some initial parameters include: the internal diameter of the liner is 97 mm, the initial magnetic field is about 5 Tesla. HE-charge total weight is about 3.7 kg. The movement of liner was recorded optically and its velocity was about 5-6 km/s. Form the photograph results the liner was compressed smoothly and evenly. The magnetic field of over 430 Tesla was measured by magnetic probes.
