Feasibility of experimental investigation of nonlinear QED processes—photon emission by electrons and pair creation by photons in strong laser field

On the basis of the theory of nonlinear QED processes occurring in collisions of high-energy electrons and γ-quanta with a strong laser pulse [1], the feasibility of their experimental investigation is discussed. The use of existing ⋍100 GeV electron beam accelerators and terawatt lasers of ultrashort pulses enables one to attain optimal values for the parameters and to have fields ⋍F_o=m²c³/ħe act on the electron. The choice and organization of laser system, synchronization of accelerator and laser operation, distributions of created γ-quanta and e⁺e⁻-pairs in different variables and parameters, their dependence on polarization of laser target and incident particles, background problems, and other questions connected with carrying out the experiments are discussed.
