An experimental study on 55fs laser driven plasma accelerator using mixedgas-jet target with varying plasma density is used to identify the role ofdifferent acceleration mechanisms, viz. Direct Laser Acceleration (DLA) andwakefield. At lower electron density electron acceleration could be attributedmainly to DLA with ionization induced injection. With increase in density,increasing role of wakefield was observed leading to hybrid regime, and atdensities higher than self-injection threshold, observed experimentally for Hetarget contribution of DLA and wakefield was found to be comparable. DominantDLA mechanism was also observed in case of pure nitrogen target. 2D PICsimulations performed using the EPOCH code corroborate the above scenario, andalso showed generation of surface waves, considered as a potential mechanism ofpre-acceleration to DLA.
