Sub-nanosecond plastic scintillator time response studies using laser produced x-ray pulsed excitation
The light emission time response of quenched NElll plastic scintillators has been measured using a streak camera (20 ps resolution) and 100 to 180 ps, 1.06 ..mu..m, laser-produced, pulsed, low energy x-ray excitation. Each light output pulse was obtained by deconvolution from the film data using the x-ray temporal response measured with an x-ray sensitive streak camera (10 ps resolution). Time response parameters are presented for benzophenone and acetophenone, quenching agents which most effectively reduce the decay time of the singlet component. Full width-half-maximums less than or equal to 260 ps were observed for NElll samples quenched with greater than or equal to 2 percent benzophenone. Results are given for unquenched samples consisting of different concentrations of butyl-PBD in PVT and for the phosphor ZnO doped with Ga.
