Abstract
We have developed the two and half-dimensional electromagnetic relativisticelectron and mobile ion cloud-in-cell (CIC) code. Mechanisms of the fastignition and interaction of ultra-intense and ultra-short pulse laser withplasma are analysed theoretically and simulated numerically using the CIC code.The strong flows of relativistic electrons and the form of the channel are observed.The results show that the superhot electron temperature is about MeV totens of MeV, and the boring velocity is 0.05c-0.1c with c being the light speed.Some preliminary scale laws are obtained. This simulation quantitativelyreproduces the experimental results at early and long times.
