Diffraction and Cherenkov radiation of relativistic electrons from a dielectric target has been proposed as mechanism for production intense terahertz (THz) radiation. The use an extremely short high-energy electron beam 4th generation light source (X-ray free laser) appears to be very promising. A moderate power the can extracted converted into THz with nearly zero absorption losses. initial experiment on observation will performed at CLARA/VELA FEL test facility in UK demonstrate principle...
Electron beams of most accelerators have a bunched structure and are synchronized with the accelerating RF field. Due to modulation electron beam frequency ν one can expect observe resonances frequencies k=k⋅ in radiation spectrum generated via any spontaneous emission mechanism (k is an integer resonance order).

Additionally, have measure neutrons gamma rays using high-resolution time-of-flight method. It has been found that ratio integral estimates between...
This paper considers the features of coherent synchrotron radiation generated when relativistic electron bunches pass field short magnets.
