Outline

Electron-ion recombination in cold magnetized plasmas shows a dramatic en-hancement of the radiative recombination rate for bare highly charged ions [1] relative to what standard radiative recombination rates predict [2]. This surprising discrepancy with theory for one of the supposedly well understood elementary quantum-electrodynamic processes has not been explained quan-titatively so far. The aim of this project is to understand the fundamental mechanism of this recombination process and the origin of the enhancement. Our inves-tigations are based on the classical chaotic dynamics in the presence of the Coulomb field of the ion and the magnetic guiding field in the electron cooler. Calculation Procedure We employ a classical trajectory Monte Carlo method (CTMC) to simulate an incoming beam of electrons from the asymptotic region to the target ion of charge Z in the presence of a homogeneous magnetic field B = Bêz given by the Hamiltonian H = p2
