Interaction of an electron with the counter-propagating electromagnetic wave is studied theoretically and particle-in-cell simulations in regime quantum radiation reaction. We find energy center laser pulse, as it a key factor for testing non-linear electrodynamics vacuum properties laser-electron collision multi-photon Compton scattering Cherenkov radiation. With multiparametric analysis we pr...

VERITAS employs a 12m segmented mirror and pixellated photomultiplier tube camera to detect the brief pulse of Cherenkov radiation produced by the extensive air shower initiated by a cosmic high-energy gamma ray. The VERITAS data acquisition system consists of a 500 Mega-Sample-PerSecond custom-built flash ADC system, which samples the Cherenkov light pulse every 2 nanoseconds. The integrated c...
