Alpha particle losses from Tokamak Fusion Test Reactor deuterium{endash}tritium plasmas
Because alpha particle losses can have a significant influence on tokamak reactor viability, the loss of deuterium{endash}tritium alpha particles from the Tokamak Fusion Test Reactor (TFTR) [K. M. McGuire {ital et} {ital al}., Phys. Plasmas {bold 2}, 2176 (1995)] has been measured under a wide range of conditions. In TFTR, first orbit loss and stochastic toroidal field ripple diffusion are always present. Other losses can arise due to magnetohydrodynamic instabilities or due to waves in the ion cyclotron range of frequencies. No alpha particle losses have yet been seen due to collective instabilities driven by alphas. Ion Bernstein waves can drive large losses of fast ions from TFTR, and details of those losses support one element of the alpha energy channeling scenario. {copyright} {ital 1996 American Institute of Physics.}
