Electron acceleration by gaussian electromagnetic beam in a stationary magnetic field

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

“…The considered method for measurement of energy of an electron beam is based on using the dependence of the condition of absorption of the circularly polarized radiation by electrons in the presence of a constant and homogeneous magnetic field on the energy of electrons ( Fig.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):…”

“…Using (29), (25) and (9) for intensity of the laser required for absorption of a photon by electron, we obtain the following approximate value: The dependence of laser intensity a las I , on energy of electrons ε in case of 2 CO and YAG Nd : lasers according to the formula (31), is illustrated in Fig. 9.…”

Acceleration of electrons by high intensity laser radiation in a magnetic field

“…The latter open the possibility for multi-photon absorption and high-rate acceleration of electrons regime (Kolomenski & Lebedev, 1962;1963;1966;Woodworth et al, 1996;Milantiev, 1997;Wang & Ho 1999;Hirshfield & Wang, 2000;Milantiev & Shaar, 2000;Konoplev & Meyerhofer, 2000;Marshall et al, 2001;Stupakov & Zolotorev 2001;Singh, 2004;2006;Cline et al, 2013;Galow et al, 2013). Due to their compactness such accelerators may be used in various applied areas, where the required energy of the electron beam is relatively small (of the order 100 M eV to 1 Gev).…”
