Dynamical behavior of plasma in linear pulse discharges of nitrogen and argon was observed electrically and optically. At the time of the first pinch of the plasma cylinder, wave forms showed various shapes and values of differentiation of the current with time change from negative to positive values, with an increase of the longitudinal magnetic field (B/sub Z/ = 0 approximately 1,150 gauss). Diameters of plasma at the time of the first pinch were measured from the photographic records taken by a high-speed streak camera. The diameters of the plasma increased and the mean constricting speeds of the plasma cylinder decreased with an increase of the B/sub Z/ field. It was assumed that in the case of argon gas discharge strong radiation flashing in a direction perpendicular to the time axis of the monochromatic streak photograph and all over the interior of the discharge tape at the time of the pinch originated from the excited radlation of neutral argon left behind the constricting main plasma.
