A Non-Thermal Plasma (NTP) is created by a diffuse discharge generated under a nanosecond range overvoltage. The influence of the anode composition on the pattern of the discharge is studied and time-resolved image of the discharge developed under these conditions are presented. The focus is made on two diffrent anode materials (copper and tungsten) leading to two distinct structures of the discharge: a well-defined and well-structured filamentary discharge and a filamentary-diffuse discharge with a glow around the anode extending until half-radius of the gap.
