The experiment was carried out on a self-made high-current pulsed electron accelerator. The cathode of the diode was made of flat brass with a diameter of 3 cm. The surface was covered with 3 mm wide concentric annular grooves at intervals of 3 mm and filled with epoxy resin uniformly. The anode is a 20 μm thick Mylar film with aluminum plating on both sides and electrically contacts the metal plate with φ26 mm holes in the middle as a drift tube entrance window. stainless steel
