First studies of 500-nm Cherenkov radiation from 255-MeV electrons in a diamond crystal

Radiation processes on acoustic superlattices

“…Note that the properties of Cherenkov radiation emitted into vacuum from a tilted plate has been investigated recently in [16,17,18] both theoretically and experimentally. In particular, the experimental results obtained in [18] for optical Cherenkov radiation from the quartz plate show a satisfactory agreement with a theoretical model based on polarization currents approach.…”

First observation of quasi–monochromatic optical Cherenkov radiation in a dispersive medium (quartz)

“…Takabayashi et al measured the angular distribution of optical ChR generated from 250 MeV electrons in a diamond target [18]. In order to extract ChR, they tilted their target such that the angle between exit surface normal and beam direction amounted to ψ = 59 • while radiation was observed at θ vac = 90 • , see Fig.…”

Особенности Поляризованного Монохроматического Черенковского Излучения В Ультрафиолетовом, Оптическом И Терагерцовом Диапазонах

“…шеней инертных газов (гелий, неон, аргон), в которых поглощение слабо [5]. В оптическом диапазоне впервые наблюдалось монохроматическое излучение в мишенях из плавленого кварца [6] и алмаза [7]. В ряде недавних работ предложено использовать импульсные пучки релятивистских электронов для генерации черенковского излучения в терагерцовом диапазоне [8].…”
