This paper studies the transport of hydrogen neutral particles towards the upstream region in the end cell of GAMMA 10/PDX by developing a neutral transport code. As a first step, a series of initial test calculations have been performed by injecting hydrogen molecules from the target plate with fixed plasma background. It has been shown that neutral particles concentrate near the target plate and reduce towards the upstream region. After these initial test calculations, the dependence of hydrogen gas puffing on the plasma parameters has also been investigated. Hydrogen gas puffing leads to a strong reduction in the ion temperature near the target plate. For the strong gas puffing case, Ti on the target plate is significantly reduced. Hydrogen gas puffing strongly enhances the momentum losses near the target plate via the charge–exchange reaction.
