Abstract
Key aspects of the dynamics of a photoelectric injector (PEI) on the Los Alamos high-brightness accelerator FEL (HIBAF) facility have been investigated using a synchroscan streak camera. By phase-locking the streak camera sweep to the reference 108.3 MHz rf signal, the variations of micropulse temporal elongations (30 to 80% over the drive-laser pulse length) and of transit times (25 ps for a 16° phase change) were observed for the first time. These results were in good agreement with PARMELA simulations.
