Volumetric recombinationis induced in He plasma by puffing of He or H_2. In the He puffing case, the reduction of the ionflux is dominated by the electron-ion recombination. In the H_2 puffing case, however, it isdominated by the molecule-assisted recombination (MAR), which is characterized by the disappearanceof the Helium Rydberg spectra and by the existence of the hydrogen negative ions. Currentachievement and the future prospect are described.展开更多
