The thresholds for the electron multiplication in both multipactor and the so-called collisional multipactor
microwave discharges are calculated by means of an individual particle model. The simulations are restricted
to low and intermediate gas pressures, where the collisional mean-free path of electrons is of the same order or
larger than the characteristic dimension of the system. Thus, the charge multiplication is caused by both the
electron impact ionization of the neutral gas and the secondary electron emission by electron collisions at the
