Abstract: Experimental studies of the spatial-time dynamics in formation and evolution of nanosecond plasma-beam discharge with a prolate slot-cathode in inert gases is investigated using a high-speed camera. Features and regularities in the dynamics of evolution of nanosecond discharge with the slot-cathode are established depending on the external conditions. As it has been shown experimentally, the first registered optical radiation of the discharge arises near cathode surface and the discharge formation starts simultaneously at the cathode slit output and between the electrodes.
