Autor: Chapman, I T, Igochine, V, Maraschek, M, McCarthy, P J, Tardini, G, Group, the ASDEX Upgrade ECRH, Team, the ASDEX Upgrade

Publikováno v: Plasma Physics and Controlled Fusion, Vol.55, No.6, June 2013, p.065009

Sawtooth control using steerable electron cyclotron current drive (ECCD) has been demonstrated in ASDEX Upgrade plasmas with a significant population of energetic ions in the plasma core and long uncontrolled sawtooth periods. The sawtooth period is
