4. Diffraction Radiation, Smith-Purcell Effect
Invited
We report on the recent studies of Smith-Purcell radiation aimed at developing a longitudinal bunch profile monitor. In particular we report on first measurements of the polarization and azimuthal distribution of the radiation. We also report on studies done in the linac of synchrotron SOLEIL to measure the distribution of Smith-Purcell radiation. Using these results we discuss the plan of...

4. Diffraction Radiation, Smith-Purcell Effect
Invited
Investigations of the Smith-Purcell radiation (SPR) were began with non-relativistic electron beams with some unexpected experimental results. Further the experimental investigations were performed with relativistic electron beams for application to beam diagnostics. Large discrepancy between different theoretical models significantly increases the role of experimental studies of this...

4. Diffraction Radiation, Smith-Purcell Effect
Invited
Polarization radiation arises when a moving charge acts upon matter by its Coulomb field, and the matter polarized by this dynamically changing field becomes a source of radiation. The charged particle itself can move uniformly and nevertheless generate electromagnetic radiation: widely known Cherenkov and Transition radiations, Diffraction radiation (DR), Smith-Purcell radiation (SPR),...

4. Diffraction Radiation, Smith-Purcell Effect
Oral
We have studied theoretically the process of generation and accumulation of coherent diffraction radiation (CDR) produced by short electron bunches in open resonator at LUCX facility of ATF KEK. In contrast with conventional applications of resonators for FELs in our case radiation is generated by electron bunches passing through vacuum holes in both mirrors (1,2).
In this report we compare...

4. Diffraction Radiation, Smith-Purcell Effect
Oral
During the interaction of the relativistic electrons field with a dielectric target various types of electromagnetic radiation, such as Cerenkov radiation, diffraction radiation, transition radiation can be generated. In this report we present the results of experimental studies of the diffraction radiation generated by relativistic electrons in a dielectric target at the interface...

4. Diffraction Radiation, Smith-Purcell Effect
Oral
When a relativistic charged particle moves near the surface, field of the particle excites oscillations of the atomic electrons, so the polarization currents arise, giving birth to the secondary electromagnetic field – polarization radiation (PR). If a charged particle moves with constant velocity along the inhomogeneous medium, PR is called diffraction radiation (DR) [1].
It is of interest...

4. Diffraction Radiation, Smith-Purcell Effect
Oral
Diffraction radiation is emitted when an electron beam passes near an edge or interface between two media with different dielectric constants. Theoretical and experimental investigation of diffraction radiation is performing at several electron accelerator facilities. If the wavelength of the diffraction radiation is longer than a pulse width of electron beam, each radiation is coherently...
