A fast computer code, SINBAD (SImplified Neutral Beam Attenuation and Deposition), which simulates the neutral particle beam injection into tokamak plasmas has been developed. The SINBAD code is based on a simplified beam model which nevertheless accurately describes the beam intensity distribution and particle trajectories in the plasma. Direct measurement of the beam deposition profile is very difficult. In this work, the beam deposition profile is investigated indirectly through its effects on neutron production and plasma energy content. A first successful method to deduce neutron emission profiles from nuclear emulsion plate measurements is presented. The procedure was tested by NEPMC (Nuclear Emulsion Plate Monte Carlo) simulations and then applied to two ASDEX discharges.
