After a vacuum failure in a tokamak, plasma runaway or plasma disruptions frequently occur
during plasma recovery, causing difficulties in rebuilding a well-confined collisional plasma …

The plasma recovery after vessel vent is studied in the EAST 2019 spring campaign. The
removal of condensate water is important for the fully superconducting tokamak. The low-Z …

Many technical improvements were achieved recently in the HT-7 superconducting tokamak,
such as ICRF boronization, new water cooling graphite limiters which is instead of …

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 …

Relativistic runaway electrons are generated in the tokamak device when electrons are
