Abstract
A new nondestructive method for measurement of the longitudinal profil e of subpicosecond electron bunches is proposed. The method is based o n measurement of spectral intensity correlations in synchrotron radiat ion. Statistical properties of synchrotron radiation produced by a bun ch passing the bending magnet are considered The signal-to-noise ratio is analyzed in terms of the degeneracy parameter. The degeneracy para meter increases approximately as a third power of the wavelength which makes the visible range of synchrotron radiation to be a natural choi ce for the spectral intensity correlation measurement. An example of t he experimental set-up is also described.
