In laser-driven wakefield, ionization induced injection is an efficient way to inject electrons in the plasma wave. A detailed study on beam dynamics under influence of loading effects, which can be controlled by concentration nitrogen impurity introduced hydrogen gas was conducted. For a specific value this percentage, final energy high-energy electron bunch becomes nearly independent trapped positions, thus leading small dispersion. We also show that emittance mainly determined process.
