An overview of TRIAM-1M experiments is presented. The current status of issues related to
steady state operation is presented with reference to the achievement of super-ultra-long …

Recent results on feedback control of the global shape of the current density profile in
discharges with lower hybrid current drive (LHCD) on Tore Supra are presented. The global …

Real-time lithium powder injection has been applied to long-pulse (> 30 s) H-mode plasmas
in EAST. This replenishes the active lithium surface that is routinely consumed by plasma …

Studies on the current-drive (CD) efficiency have been carried out in the FTU tokamak with 8
GHz lower-hybrid waves up to line-averaged plasma density ne> 1× 10 20 m− 3. High …

Using a 2 MW 2.45 GHz lower hybrid wave (LHW) system installed in experimental
advanced superconducting tokamak, we have systematically carried out LHW-plasma …

Control of impurities, fuel recycling and hydrogen content by lithium evaporative coatings
and real-time lithium powder injection (LPI) in EAST are studied for high performance H …

The turbulence in the scrape-off layer (SOL) plasma of FTU is characterized in order to
assess its effect on the current drive efficiency of the lower hybrid (LH) waves. Amplitude …

The lower hybrid current drive (LHCD) system for superconducting steady state tokamak-1
(SST-1) machine is in advanced stage of integration and commissioning. The system is …

Controlled modification of the radial profiles of the plasma current, electron temperature and
density was achieved in the ASDEX divertor tokamak with lower hybrid waves. Variation of …

Thanks to the tail of fast electrons generated by the lower hybrid (LH) waves, the plasma
conductivity changes significantly with respect to the ohmic heating status (Fisch 1985 Phys …
