DOI: 10.1016/j.fusengdes.2021.112488
Abstract: Abstract For disruptions without mitigation, a large amount of thermal energy and poloidal magnetic energy will be dissipated inside the vacuum vessel (VV). A slow current quench may be accompanied by a large halo current,… read more here.

DOI: 10.1088/1741-4326/abb79c
Abstract: A major disruption event in a tokamak is generally observed to be a two-step process, in which a healthy tokamak plasma ceases abruptly by first losing its temperature, known as ‘thermal quench’ followed by the… read more here.

DOI: 10.1088/1741-4326/ad502b
Abstract: ASDEX Upgrade has developed multiple massive gas injection (MGI) scenarios to investigate runaway electron (RE) dynamics. During the current quench of the MGI induced disruptions, Alfvénic activity is observed in the 300–800 kHz range. With… read more here.
