Explosive Implosion Magnetic Flux Generator (EIMFG) is a kind of extreme condition dynamic technique and could realize millions of GPa on large volume (10^-1cm³ order) sample materials like hydrogen and its isotope. The Institute of Fluid Physics, Chinese Academy of Engineering Physics (IFP, CAEP) has developed EIMFG technologies in recent years and CJ series EIMFG device have been built up and over 900T of axial magnetic field were already obtained which means millions of GPa of isentropic compression could be possibly realized.
As to the experimental research on metallic phase transition of Hydrogen and deuterium by using EIMFG, a high pressure loading control method was put forward by adjusting magnetic field and sample chamber structure in the process of EIMFG. The sample’s temperature and pressure will be controlled effectively by this method. An instant optical reflectivity measurement technique will be developed as a characterization method of metallization of hydrogen and its isotope. The condition of Liquid to Liquid Insulator to Metal Transition (LL-IMT) of hydrogen and its isotope will possibly be realized. More important, an extreme physical state of pressure large than 500GPa, temperature low than 1000K will probably realized in large hydrogen sample and new mechanism and phenomena of metallization will be explored in the future.
