| Abstract: High energy electron radiography technique, a new scheme to diagnose the high energy density matter, was proposed in 2012 by Institute of Modern Physics (IMP). The high energy density physics experimental research needs a fast, temporal and 3-dimensional diagnostic system to monitor the density evolution during ~200ns compression time. A prove-of-principle experiment was carried out on the 50MeV electron linac accelerator of Tsinghua University. 1.5um spatial resolution was measured by imaging a TEM grid with magnetic lens imaging system. Meanwhile, the simulation research on the interaction between the high energy electron and dense matter was also implemented to verify that the 1~2GeV electrons could penetrate the 200ug/cm2 dense matter with relative revolution in both spatial and time dimensions through an appropriate magnetic imaging system. | ||
