Description

Beam ion losses from the National Spherical Torus Experiment (NSTX) under a variety of plasma conditions have been modeled using the EIGOL code. This code incorporates the beam deposition and the full gyroorbit of the ions. EIGOL results indicate that 42% of the beam power will be lost to the walls for an equilibrium with β=40%, IP=1 MA, BT=0.3 T, and q0=2.6. The high harmonic fast wave (HHFW) antenna, because it is at the midplane and is closer to the plasma than any other structures, will absorb most of the power from the escaping beam ions. (author)
