Twenty four 10 mm bore flashlamps ranging from 6 inch arc length to 56 inch arc length were life tested at high fractions of explosion energy. These tests indicate that previously established lamp life prediction rules developed for smaller lamps can be applied to large lamps without serious error. A magnetic force analysis was made for linear flashlamps in a close packed cylindrical array. It was established that the magnetically induced tensile stress in the lamp envelope is reduced by as much as a factor of 15 if the currents in adjacent lamps flow in opposite directions rather than in the same direction. A variety of lamps mount and high voltage insulation systems were designed and tested. A ten lamp test fixture was designed, constructed, and tested with ten lamps and a total stored energy of 45 kilojoules for 500 pulses without failure.
