The EPOC(Equivalent Physics Of Confinement)scenario for the proof of principle of high gain inertial confinement fusion is presented, with the concept of "hydrodynamically equivalent implosions" playing a key role. Scaling laws on the target and confinement parameters are derived by applying the Lie group analysis to the PDE(Partially Differential Equations)chain of the hydrodynamic system. The results shows that the conventional scaling law based on adiabatic approximation differs significantly from the scaling law that considers electron heat conduction and other energy-transport effects. Confinement plasma parameters of the hot spot, such as the central temperature and the areal mass density at peak compression, are obtained with a self-similar solution for spherical implosions. Ignition energy scaling in terms of the implosion velocity and the isentrope parameter is also discussed by reviewing several recent works.
