Abstract

Interferometry for weakly relativistic plasmas is studied in this paper. It is shown that the phase difference in plasma and vacuum propagation becomes small due to the relativistic mass correction of electrons. The axisymmetric density profile obtained from the usual Abel inversion equation also becomes small by the correction factor, which is 1 ∼ 1.3 for T_e = 0 ∼ 60 keV. It is shown that we have to use the Abel inversion equation to take into account the relativistic mass correction of electrons in order to reconstruct the correct density profile.
