Time resolved spectroscopy of large bore Xe flashlamps for use in large aperture amplifiers

Abstract

Time resolved spectroscopy was performed on 13-mm xenon filled flashlamps. The use of a well-characterized system allowed the acquisition of absolute radiometric data. The data were compared to the predictions of a phenomenological flashlamp model and differences noted. Specifically the arc for equal currents is not the same for dI/dt > 0 and dI/dt < 0, the continuum is a stronger function of current density than the model indicated, and different lines, linewidths, and line intensities were found.
