As the results of worldwide collaboration, empirical scaling laws on plasma energy confinement time have been established in tokamak plasmas, and these laws have been applied for designing fusion rectors and nextstep devices such as ITER. To assure empirical scaling laws through experimental data, the scale invariance of the basic equations has been introduced, where several non-dimensional parameters such as normalized Larmor radiusρ, beta value β and normalized collision frequency υ have been identified. In particular, because the normalized Larmor radius is the most important parameter for extrapolating future devices, the ρ dependence of the energy confinement time, which is classified into Bohm and GyroBohm characteristics, has been studied intensivery. To explore the plasma confinement property, so-called dimensionally similar discharge, in which other non-dimensional parameters excepting for the ρ value have been unchanged between two different discharges, has been conducted.
