Abstract： We have developed the two and half-dimension electromagnetic relativistic electron and mobile ion cloud-in-cell (CIC)code. Mechanisms of the fast ignition and interaction of ultra-intense and ultra-short pulse laser with plasma are analysed theoretically and simulated numerically using CIC code.Strong flows of relativistic electron and form of the channel are observed. The results show that the temperature of superhot electron is about MeV to tens 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 quantitatively reproduces the experimental results at early and long times.
