Impact of field ionization on the velocity of an ionization front induced by an electron beam propagating in a solid insulator
B Frolov1, S Krasheninnikov1, A Kemp2 and T Cowan2
Show affiliationsThe propagation of an intense electron beam through a solid density insulator is analysed. The asymptotic behaviour of the front velocity is found for large beam densities. We show that at high beam densities the front velocity starts to fall when the induced E-field becomes strong enough to neutralize itself (through field ionization followed by self-consistent charge neutralization). We also show that the effect of the polarization current (caused by the E-field removing electrons from atoms) on the magnitude of the ionization front velocity, although noticeable, does not change the qualitative picture derived when neglecting it.
