The simulation qualitatively reproduces the experimental anisotropy of the photon spectral temperature previously reported. The effects of variations in the magnetic field minimum Bmin and in the extraction peak on both the electron energy distribution function and the Bremsstrahlung emission are also investigated and reported. The simulation results confirm that only changes in Bmin influences the hot energy tail of the EEDF. The MC high electron statistics allows studying with unprecedent details the location and mechanism responsible for the hot electrons generation in ECRIS, highlighting the crucial role of Bmin in this process.
