1. Characteristics of synchrotron radiation

1.1 Emission principle

Light emitted by charged particles, such as electrons or positrons (positively charged "electrons") accelerated to close to the speed of light, is called synchrotron radiation. The basic principle of this emission is well interpreted in Maxwell's electromagnetic wave theory . Any charged particle subjected to acceleration emits electromagnetic radiation. When acceleration is low (classical mechanics approximation), the radiation is emitted isotropically throughout space and is almost monochromatic; this is the case with radio antennas (figure
