Outline of Final Research Achievements

We investigated long wavelength radiation from a superconducting three-pole wiggler section. The following important theoretical and experimental results were obtained. As the experimental results, (1) clear and simple observation method for edge radiation was established and (2) an increase effect of edge radiation at superconducting three-pole wiggler section was observed by usage of the observation method. As a theoretical result, the increase effect was understood as interference effect of edge radiation between upward and downward straight sections of the wiggler. Basing on the interference model, we proposed further large increase effect of edge radiation, which was obtained by periodic alignment of three-pole wiggler.
