Analysis for magnetic and radiation spectral properties of undulators at HiSOR

A compact, racetrack type storage ring HiSOR has been constructed at Hiroshima Synchrotron Radiation Center. A linear undulator and a new type of helical/linear undulator were installed at the two straight sections of HiSOR. Their magnetic fields were measured for different configurations and gaps. The analysis of experimentally measured magnetic field data and radiation spectra are made for HiSOR undulators and presented in this report.
