 For 100 J, piker second duration poles from Omega EP laser facility was used to accelerate electron beams with 505 plus or minus 75 mV energy and 140 plus or minus 30 NC charge from a low-density plasma target using direct laser acceleration, DLA, method. The dominant acceleration mechanism is confirmed to be DLA and the effect of quasi-static channel fields on energetic electron dynamics is examined in self-consistent two-dimensional particle-insult simulations, where a strong channel magnetic field, self-generated by the accelerated electrons, plays a comparable role to the transverse electric channel field in defining the boundary of electron motion.
