A SYSTEM FOR MEASURING NANOSECOND ATOMIC LIFETIMES.
Abstract
A multi-channel time interval recording system used for radiative lifetime measurements in the vacuum ultraviolet is described. This recording system exhibits an overall 'prompt' decay lifetime of 400 psec. The effect of differential nonlinearities is eliminated by the simultaneous, absolute calibration of each channel width, accomplished with the aid of a crystal time standard, a scaler, fast inhibit logic, and a random pulse source. Coincidence selection before time-to-height concersion allows repetition rates to 10 MHz. Pulsed electron excitation allows studies of atomic and molecular optical radiation and dissociative excitation. (Author)
