Description
Utilizing the relativistic invariance of the parameter $\chi=\gamma E/E_{0}$, ultrarelativistic particles in strong crystalline fields of the order $10^{11}$ V/cm enable investigations of processes in fields of the order the QED critical field $E_{0}=m^{2}c^{3}$/eħ=1.32·$10^{16}$ V/cm (with a corresponding magnetic field of $B_{0}$=4.41·$10^{9}$ T) in the particle rest frame. In the framework of the CERN NA63 experiment we have obtained experimental results on e.g. quantum synchrotron radiation emission, coherent pairs, radiation reaction and recently trident production in such fields. An overview of results from the CERN NA63 experiment is presented.
