Abstract

Streak camera with spiral scanning will allow measuring a single light signal with duration up to ten nanoseconds with sub-picoseconds time resolution during all signal duration by means of using the whole 2D surface of screen. For creation such a streak camera it is necessary to have a high density of photoelectron beam in order to have small beam size and enough quantity of electrons in the resolution element. But the beam density increasing is limited by different effects including temperature relaxation. Quite the contrary in typical streak cameras the beam density is reduced down to single photoelectrons in the resolution element and then the number of electrons is integrated either on recurring signal or along streak. Another way is the significant increase of electrons energy. This idea has been realized in the streak camera with photoelectron energy up to 90kV and circular scanning by means of high quality RF cavity. The results of testing of this streak camera are presented. The design of streak camera with spiral scanning is presented.
