Spectral phase interferometry for direct electric-field reconstruction of synchrotron radiation
Takao Fuji, Tatsuo Kaneyasu Masaki Fujimoto, Yasuaki Okano +7
Ultraviolet and extreme ultraviolet electric-fields produced by relativistic electrons in an undulator of a synchrotron light source are characterized by using spectral phase inter…
Angular Momentum of Twisted Radiation from an Electron in Spiral Motion
M. Katoh, M. Fujimoto, H. Kawaguchi +7
We theoretically demonstrate for the first time that a single free electron in circular/spiral motion emits twisted photons carrying well defined orbital angular momentum along the…
Twisted Radiation by Electrons in Spiral Motion
M. Katoh, M. Fujimoto, N. S. Mirian +11
We theoretically show that a single free electron in circular/spiral motion radiates an electromagnetic wave possessing helical phase structure and carrying orbital angular momentu…
Gamma ray vortices from nonlinear inverse Compton scattering of circularly polarized light
Yoshitaka Taira, Takehito Hayakawa, Masahiro Katoh
Inverse Compton scattering (ICS) is an elemental radiation process that produces high-energy photons both in nature and in the laboratory. Non-linear ICS is a process in which mult…
Present status of source development station at UVSOR-III
Najmeh Sadat Mirian, Jun-ichiro Yamazaki, Kenji Hayashi +6
Construction and development of a source development station are in progress at UVSOR-III, a 750 MeV electron storage ring. It is equipped with an optical klystron type undulator s…
