Enhanced effectivity of autoresonant acceleration of electrons by Gaussian laser radiation

On possibility of measurement of the electron beam energy using absorption of radiation by electrons in magnetic field

“…1). Acceleration of electrons with a high gradient of acceleration by means of consecutive multiphoton absorption in a constant magnetic field was discussed in many papers [4][5][6][7][8][9][10][11][12]. However, the feasibility of measurement of an electron beam energy by the radiation absorption method is much simpler than the acceleration of electrons by the same method, because for measurement of the electron beam energy it is enough to have absorption of one or several photons.…”

“…It is known that in a field of circularly polarized electromagnetic wave and in a magnetic field, the electrons can be accelerated due to absorption of laser photons [4,3,7,[9][10][11]24]. Intensity of the laser required for RA of photons by an electron can be found using the classical formula for the growth of electron energy [4,6,8,[10][11][12] and by using the formulas (1), (4):…”
