Magnetic Field Discontinuity as a New Brighter Source of Infrared Synchrotron Radiation

Abstract

Strong emission of highly collimated infrared radiation demonstrates the presence of dipole edge emission and transient undulator radiation emission. The photon flux and spatial distribution for the Super-ACO sources (both dipole edge and wiggler) including coherence effects have been evaluated using the exact expression for the emission of a charged particle. The excellent agreement between these results and measurements performed at the SIRLOIN (Spectroscopie en Infrarouge LOINtain) beam line provides a new level of understanding of infrared synchrotron radiation.
