Abstract

Mach probe characteristics are evaluated by using a directional Langmuir probe (DLP) in a fast flowing plasma produced by a magneto-plasma-dynamic arcjet (MPDA). The obtained data are compared with Hutchinson's simulation results which are calculated using a particle-in-cell (PIC) code in an unmagnetized plasma [I.H. Hutchinson, Plasma Phys. Control. Fusion, 44 (2002) 1953]. The experimentally obtained data are in good agreement with the simulation results in the wide range of M_i (0.4 < M_i < 1.7). Two types of the Mach probe, where the probe tips are facing to up-down directions and para-perp ones, are compared with model formulas and the simulation results. Good agreements are obtained among these data and calibration factors to determine the Mach number are evaluated.
