Comparison of plasma start-up with high Z and low Z first wall in WEST by C. Guillemaut, K. Afonin, G. Bodner, J. Bucalossi, Y. Corre, P. Devynck, A. Diallo, M. Diez, N. Fedorczak, A. Gallo, B. Guillermin, V. Lapleigne, R. Lunsford, P. Maget, J. Morales, Ph. Moreau, the WEST Team, the EUROfusion Tokamak Exploitation Team

“…In this context, the present work focuses on the correlations between first wall impurity sources and total radiated power during plasma start-up in the tungsten (W) Environment in Steady-state Tokamak (WEST). The objective is to highlight experimental indications for a preferable combination of start-up plasma scenario and first wall materials. …”

Tungsten impurity reduction by ICRH in a high power injection and high performance H-mode discharge on EAST by Zhen Zhou, Shengyu Shi, Ling Zhang, Tao Zhang, Xiaohe Wu, Yunxin Cheng, Wenmin Zhang, Chaowei Mai, Shengyu Fu, Yifei Jin, Xiang Jian, Kaixuan Ye, Lin Yu, Ziqiang Zhou, Jiuyang Ma, Shuqi Yang, Kangning Geng, Gongshun Li, Jia Huang, Fei Wen, Yunfeng Liang, Xiang Gao

“…The decrease in tungsten (W) content with the higher ion cyclotron resonance heating (ICRH) power is observed and explained for the first time in a high power injection ( P _inj > 10 MW), high performance ( β _N ∼ 2, β _P ∼ 2.8, n _e / n _GW ∼ 80%, f _BS ∼ 60%) H-mode discharge on experimental advanced superconducting tokamak. Unlike the previous phenomenon of electron cyclotron resonance heating core W control (Shi et al 2022 Nucl. …”
