Instrum. 56, 871 (1985);The ultrafast streak camera is presently the only comprehensive temporal diagnostic tool available for laser-fusion studies. An internally emplaced CCD readout system has been designed to minimize the data reducing complexity, cost, and time delay associated with the present phosphor/intensifier/film readout technique. Experimental results using the front-illuminated Fairchild 202 CCD and the back-illuminated RCA SID 52501 CCD for direct imaging of the streak-camera photoelectrons are presented. The important sensor requirements which optimize the performance of the CCD in the streak-camera application have been defined.

The light emission time response of quenched NE1T1 plastic scintillators has been measured using a streak camera (20 ps resolution) and 100 to 180 ps, 1.06 um, laser-produced, pulsed, low energy x-ray excitation. Each light output pulse was obtained by deconvolutlon 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 wTdth-half-maximums <_ 260 ps were observed for Nf.111 samples quenched with i 2% benzophenone. Results are given for unquenched samples consisting of different concentrations of butyl-PBD in PVT and for the phosphor ZnO doped with Ga.

A streak camera technique with temporal resolution of 20 ps has been used to measure the fluorescence properties of several subnanosecond plastic scintillators. The method employs a vacuum light pipe coupled to an optical streak camera. The scintillators are excited by a 200-ps x-ray pulse generated by a 1.06-microm Nd:YAG laser focused onto an iron target. The time history of the low-energy x-ray pulse is measured with an x-ray streak camera. Results are given for NElll plastic scintillators doped with benzophenone or acetophenone, for PVT doped with butyl-PBD, and for a ZnO phosphor doped with Ga.
