The results of particle-in-cell simulations of a negative neutral beam heated Alfvén-mode
experiment in the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-
60U)[H. Ninomiya et al, Fusion Sci. Technol. 42, 7 (2002); A. Kitsunezaki et al, Fusion Sci.
Technol. 42, 179 (2002)] are presented. They seem to match quite well the dynamics of the
abrupt large-amplitude event (ALE) experimentally observed in the reference JT-60U
discharge. The time scale and frequency spread of the ALE are well reproduced too. The …
