Abstract
Codes NFREYA and TORUS II are used to calculate the α - particle containment and loading as well as the power deposition and the driven current in ST40 high field spherical tokamak. First orbit approximation and complete slowing down orbits, needing 6.25 107 computed orbit points approximately, were used. We show that for ST40 conditions, the containment depends mainly on the peaking parameter of the density profile (p~2) which can be reached by the pellet injection. The maximum containment in the case of slowing down orbits is around 0.25 agreeing roughly with the first orbit guiding center calculations.
