The sputtering yields of a tungsten target by hydrogen isotopes in the energy range of bombarding particles from 50 eV to 100 eV, as well as the dependence of the sputtering yields on the angle of incidence of the beam on the target and the energy and angular distributions of sputtered particles are obtained by the code developed by us. The strong influence of the type of surface barrier on the results of calculation of the sputtering yield, as well as on the characteristics of sputtered particles is demonstrated. The results obtained make it possible to more accurately assess the tungsten impurity inflow into the hot plasma zone of tokamak.
