Experimental study of edge radiation at HiSOR

The measurements of spectral-angular distributions of edge radiation emitted at the fringe fields of two bending magnets are reported. These studies were conducted at HiSOR electron storage ring (Hiroshima, Japan). The radiation was observed in the near infrared, visible and near ultraviolet ranges. The recorded images, both horizontally and vertically polarized, are compared with the numerically simulated distributions of the edge radiation. Good agreement is found between the measured and calculated characteristics of edge radiation.
