New generation streak camera design and investigation

The only method for electron bunch duration monitoring with resolution of the order of 10 fs and less is the method of photochronography of the bunch incoherent radiation in the frequency range, for example, of visible light and at realizing streak camera with new principles of its operation [1]. In the paper the streak camera design for measuring both the electron bunches and x-ray pulses with the mentioned temporal resolution is presented. The results of the camera investigation with photoelectron dynamics simulation taking into account space-charge effect and influence of the surface roughness of a spherical photocathode of the 20-50 micrometers radius (forming a modulating gap of spherical configuration) on the camera resolution are presented and discussed.
