Pdf a low cost cherenkov imaging system for tev gammaray. The underlying idea is to consider that the power radiated by the charge is equal to the work done by the radiation reaction force. Cherenkov radiation, also known as vavilovcherenkov radiation, also spelled cerenkov is electromagnetic radiation emitted when a charged particle such as an electron passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. In this work we analyse the cherenkov effect for nonrotating extended charges. The angle takes on a maximum as the particle speed approaches the speed of light. The cherenkov angle is zero at the threshold velocity for the emission of cherenkov radiation. The cherenkov effect for nonrotating extended charges. Hence, observed angles of incidence can be used to compute the direction and speed of a cherenkov radiationproducing charge.
The phenomenon was discovered by the soviet physicist pavel a. Please note, this figure shows the ideal case of no dispersion, which means that the refractive index n is independent of the wavelength. In reality n will depend on and hence the wave front governed by group velocity will no longer be perpendicular to the direction of the radiation governed by phase velocity.

Cherenkov radiation, light produced by charged particles when they pass through an optically transparent medium at speeds greater than the speed of light in that medium. The charged particles polarize the molecules of that medium, which then turn back rapidly to their ground state. We obtain the energy radiated per unit path length per unit frequency by the charge facing the cherenkov effect as a radiation reaction problem.

A low cost cherenkov imaging system for tev gammaray astronomy. The characteristic blue glow of an underwater nuclear reactor is a completely normal phenomenon due to cherenkov radiation.
