The translating velocity of a field-reversed configuration plasma is controlled using a pulse mirror field. Numerical calculations are carried out, using a flux-conserving moving mirror coil, to simulate the motion of the plasma subject to the pulse field. The calculations suggest that it is possible to stop the plasma smoothly without reflection under the pulse mirror coil when the strength of the mirror is changed depending on the velocity of the plasma. In the experiment, the pulse field is produced by a current flowing in a one-turn coil installed inside a theta-pinch coil. It is demonstrated that the translating plasma passing under the one-turn coil is reflected and stops depending on the strength of the pulse field. The optimum strength of the field to stop the plasma without reflection is in good agreement with the estimation of the calculations.
