Abstract :
Method for measurement of electron beam divergences and transversal sizes with visible range edge radiation (ER) is discussed. Intensity distribution of the ER generated by an infinitely thin electron beam at two adjacent bending magnet edges in a storage ring represents a system of concentric interference rings. The real beam divergences and transversal sizes smooth off the interference pattern; information on the extent of the smoothing off, being processed numerically, allows to determine the above mentioned beam parameters. Precise computing technique of the ER intensity distribution with regard to finite beam emittance is presented. The results of simulations illustrating the application of the method for 450 MeV electron storage ring Siberia-1 are exhibited
