High-quality multi-GeV electron bunches via cyclotron autoresonance — •jianxing li¹, benjamin j. galow¹, yousef i. salamin^1,2, zoltán harman¹, and christoph h. keitel¹ — ¹Max-Planck-Institut für Kernphysik, Heidelberg, Germany — ²Department of Physics, American University of Sharjah, Sharjah, United Arab Emirates

Autoresonance laser acceleration of electrons is theoretically investigated using circularly polarized focused Gaussian pulses. Many-particle simulations demonstrate feasibility of creating over 10-GeV electron bunches of ultrahigh quality (relative energy spread of order 10⁻⁴), suitable for fundamental high-energy particle physics research. The laser peak intensities and axial magnetic field strengths required are up to about 10¹⁸ W/cm² (peak power ∼10 PW) and 60 T, respectively. Gains exceeding 100 GeV are shown to be possible when weakly focused pulses from a 200-PW laser facility are used. In our parametric study of this acceleration scheme, substantial challenges still need to be dealt with, especially on the road to realizing experimentally the required high magnetic field strengths and laser powers.^[1]
