Session KP01 - Poster Session III.
POSTER session, Tuesday afternoon, March 23

Detailed understanding of energetic particle confinement, transport and losses in low aspect ratio tokamaks, such as NSTX and MAST, is necessary for understanding and planning future experiments. In this presentation requirements for plasma equilibrium to confine fast particles are analyzed and compared with ones in tokamaks. Beam ion losses are studied using the ORBIT code. Losses of fusion products (tritium and proton ions), having large gyro radius, and their distribution in pitch angle and poloidal angle are simulated by new code LARMOR. The opportunity to use the diagnostic of lost fast particles by measuring their energy spectrum and flux pitch angle distributions is discussed in order to be able to reconstruct basic plasma parameters, such as temperature profile, fusion products source profile, plasma current and others.
