Abstract

A Monte Carlo (MC) code is used to investigate the bremsstrahlung x-ray emission of an electron cyclotron resonance ion source (ECRIS) and its dependence on the axial magnetic confinement. The x-ray spectral temperature Ts measured with the simulations is in fair agreement with previous experiments. The dependence of Ts on the minimum magnetic field of the configuration Bmin is corroborated, also observing that the ion extraction peak field Bext has no influence on temperature. Details on the mechanism generating the hot electron population responsible for the change in spectral x-ray temperature as a function of Bmin are proposed, based on an in-depth investigation of the electron population with the MC code using a high statistics.
