Abstract
The intensity and energy spatial distributions of collimated laser Compton scattering (LCS) γ-ray beams and of the associated bremsstrahlung beams have been investigated as functions of the electron beam energy, electron beam phase spac...

An undulator generating a magnetic field whose longitudinal profile is arbitrarily varied has been developed, which is one of the key components in a number of proposed new concepts in free-electron lasers. The undulator is composed of magnet modu...

A quasi-isochronus operation is one of the operation modes of NewSUBARU, a 1.5 GeV VUV storage ring. NewSUBARU has six invert bending magnets to control the momentum compaction factor. The aim of this research is to explore the extreme reduction o...
The NewSUBARU storage ring has an 11 m long undulator. It is a permanent magnet planner undulator, consisting of eight units. We measured and adjusted its magnetic field distribution to minimize the imperfection fields mainly by an in-situ sorting...
