Status of a radio-frequency-based streak camera with subpicosecond time resolution

Usage of a cavity with a high quality factor in a streak camera (SC) allows us to increase the energy of electrons up to 100 keV and therefore to redu ce the influence of some of the effects that limit the SC time resolution. Time resolution up to 1.4 ps on a prototype of a radio-frequency-based SC ( RFC) with circular scanning was demonstrated earlier. Following this, the n ew RFC was produced. The possibility of achieving a time resolution of 0.6 ps for a 350-ps single light signal is demonstrated. Preparation for experi ments with spiral scanning (sub-ps time resolution for 10-ns process durati on) is in progress.
