Method of Bunch Radiation Photochronography With 10 Femtosecond and Less Resolution

Abstract

The success in creation of the proposed facilities, where the required electron bunch duration can be of about 100 fs and less, will be depend directly on the ability to measure the bunch longitudinal profile with resolution of the order of 10 fs and less. The only method for the bunch monitoring with the mentioned temporal resolution is the method of photochronography of the bunch incoherent radiation, for example, in the frequency range of visible light and at realizing streak camera with new principles of its operation. Results of novel type streak camera design and its investigation with photoelectron dynamics simulation taking into account space-charge effect are presented.
