The Lethality Test System (LTS) at the Los Alamos National Laboratory is an electromagnetic launcher system that is presently being constructed to perform impact experiments. This system will be capable of accelerating 20 to 30 g projectiles to 15 km/s in 4 ms. To achieve this velocity the power system must supply a current waveform that rises from approximately 1 MA to 1.3 MA during the acceleration period. A three -stage, distributed energy storage system has been chosen for the base design. These stages must deliver approximately 30 mJ to the railgun during projectile acceleration. A railgun power supply has been designed that utilizes traction motors, vacuum interrupters and pulse transformers. An assembly of 28 traction motors, which store approximately 75 MJ, energize the primary windings of three pulse transformers at a peak current of 50 kA. At peak current an array of vacuum interrupters disconnects the transformer primary windings and forces the current to flow in the secondary windings. The secondary windings are connected directly to the railgun and require no opening switches. By staging the vacuum interrupter openings, a 1 MA to 1.3 MA ramped current waveform can be delivered to the railgun.
