The need to do high precision, time-resolved, optical and x-ray measurements at the Nova Laser System at the Lawrence Livermore National Laboratory has led to increased demands on the triggering requirements of the Target Diagnostics instruments. These diagnostics require a fast trigger that is synchronous with the target irradiation. Previously, oscilloscopes and streak cameras shared the same triggering system. The relatively short temporal window of the streak cameras and the need for pre-shot system monitoring and post-shot data analysis justified the development of an improved triggering system. This paper discusses a system dedicated to triggering streak cameras on the Nova system which provides 16 individually adjustable triggers that are synchronous with the incident laser beam to within 100 ps. This system includes the capability to monitor the sweep circuit of each camera to detect a difference in trigger timing with a resolution of 50 ps on both target shots and dry runs. Various other parts of the diagnostic/triggering system are also routinely monitored.
