FIELD: microelectronics. SUBSTANCE: broad-aperture flash tube has discharge chamber filled with working mixture and provided with outlet window. Chamber accommodates round cathode, anode, and spark gaps. Cathode is solid structure shaped so that uniform electric field is built up. Anode is of cellular type transparent to 70% with cell size not over 0.1 of distance between cathode and anode. Spark gaps are uniformly distributed over anode edge. EFFECT: enlarged diameter of output bean, improved reliability. 2 dwg
