An electromechanical shutter mechanism capable of achieving shutter speeds up to 50 m/sec was designed, constructed and tested. An exploding wire was used to generate a cylindrically imploding blast wave. The input energy capability was 200 joules. The explosion chamber was designed to make use of the reflection of the finite-energy imploding blast wave at the base of the shutter in the track. A qualitative correlation between energy input to the explosion and the kinetic energy of the shutter was made for different wire resistances. A shutter to be used as a component cf an interferometer was constructed and tested. This shutter can achieve very rapid closed-open-closed operating times.
