This paper presents a simple phenomenological model and detailed simulation studies of the breakdown of a gas under the simultaneous action of electric and magnetic fields. In deriving expressions for the breakdown voltage variations of both the ionization coefficient and the secondary electron yield in a magnetic field are taken into account. Calculations were carried out by using the XOOPIC code with the old and the improved secondary emission models adjusted to involve the influence of the magnetic field on the secondary electron production. It was shown that the incorporation of the variation of the secondary electron yield with magnetic field leads to the better agreement with existing experimental results.
