Abstract A study was conducted on the dependence of discharge efficiency upon discharge voltage, its spatial distribution, and distribution of electron beam injected in Ne‐Xe mixture discharge lamp through 2‐D fluid simulation and 1‐D particle‐in‐cell simulation combined with a fluid model, respectively. Based on the simple calculation from cross‐section and electron beam energy, the optimum energy of the injected electron beam for high efficient light source is about 14∼16eV in the case of pure Xe. The simulation results also show the similar characteristics to the estimated data in discharge efficiency.
