A Monte Carlo code(MCHGAS)has been developed to investigate the neutralparticle transport.The code can calculate the radial profile and energy spectrum of neutralparticles in cylindrical plasmas.The calculation time of the code is dramatically reduced whenthe Splitting and Roulette schemes are applied.The plasma model of an infinite cylinder isassumed in the code,which is very convenient in simulating neutral particle transports in smalland middle-sized tokamaks.The design of the multi-channel neutral particle analyser (NPA) onHL-2A can be optimized by using this code.
