Transition of the light velocity in the Vavilov - Cerenkov effect
Accelerated and decelerated motions of a charged point particle inside medium are studied. It is shown explicitly that in addition to the bremsstrahlung and Cerenkov singular waves, previously unknown electromagnetic singular wave should be observed. It arises when the charge velocity coincides with the light velocity in medium. This wave has the same singularity as the Cerenkov one and, theref...
متن کاملCalibration sources of Cerenkov radiation
We report on attempts to construct and simulate low intensity sources of Cerenkov radiation with accurately known spectral intensity. These sources will be used to calibrate photomulti-pliers for the Sudbury Neutrino Observatory. We have used ^Sr as a radioactive beta source located at the center of a sphere of ultraviolet transparent acrylic. The production of Cerenkov radiation by stopping el...
متن کاملCerenkov radiation in photonic crystals.
In a conventional material, the coherent Cerenkov radiation due to a moving charged particle is associated with a velocity threshold, a forward-pointing radiation cone, and a forward direction of emission. We describe different behavior for the Cerenkov radiation in a photonic crystal. In particular, this radiation is intrinsically coupled with transition radiation and is observable without any...
متن کاملCerenkov line-like radiation, the extended and improved formulae system
You & Cheng (1980) argued that, for relativistic electrons moving through a dense gas, the Cerenkov effect will produce peculiar atomic and/or molecular emission lines–Cerenkov lines. They presented a series of formulae to describe the new line-mechanism. Elegant experimental confirmation has been obtained by Xu. et al. in the laboratory which definitely verified the existence of Cerenkov lines...
متن کاملProbing the Brans-Dicke Gravitational Field by Cerenkov Radiation
The possibility that a charged particle propagating in a gravitational field described by Brans-Dicke theory of gravity could emit Cerenkov radiation is explored. This process is kinematically allowed depending on parameters occurring in the theory. The Cerenkov effect disappears as the BD parameter ω → ∞, i.e. in the limit in which the Einstein theory is recovered, giving a signature to probe ...
