Abstract:

Real-Time mass loss instrumentation has been developed for the Defense Nuclear Agency to provide a means of studying laser and target interaction during target illumination by continuous wave CW high energy lasers. Mass loss measurements that were addressed in this program are the transients that occur during and immediately following coupon illumination. The high frequency inertial mass measurement technique furnishes rapid mass measurements required to resolve mass transients. The instrumentation possesses resistance to impulsive forces present during material ablation allowing continuous measurements during an event. Tests performed using the prototype balance and a 50 kW CW laser demonstrated this concept to be valid. Present mass resolution is or - 600 micrograms at a time resolution of 500 microseconds. There do not appear to be any technological barriers that would prevent significant time and mass resolution improvements.
