摘要：

The ion heat pulse after a sawtooth crash is studied by a time-of-flight (TOF) neutral measurement. A rapid change of the bulk ion energy distribution near the edge is observed after a sawtooth crash. The delay time is measured, and the effective measuring position is estimated by a neutral transport code. Then a transient ion thermal conductivity, chi(i)(HP), of about (7-18) m(2)/s is evaluated for the low confinement mode (L-mode) plasma. The simple diffusive model with constant chi(i)(HP), however, does not explain the amplitude of the pulse in the ion energy distribution. (C) 1996 American Institute of Physics.
