New principles in photochronography of femtosecond resolution

Abstract

For reaching temporal resolution of about 1 fs in a time converting chronography of pulsed photon radiation in a range of visible light a new principle in the chronography consisting in simultaneous acceleration and longitudinal modulation of photoelectrons for the shortest time (about 1 ps) and at the moment of their escaping from a photocathode are proposed and considered. Photoelectron camera realizing the new principles and using the gold photocathode for soft-x-ray pulse registration with temporal resolution of 100 fs at the photoelectron bunch population of about 1000 electrons will be also discussed.
