abstract = {A systematic study of disruption-generated runaway
electrons has been performed in the J-TEXT tokamak. During
the intended disruption by the argon injection in J-TEXT,
the runaway electron plateau is more easily obtained with a
higher loop voltage and shorter onset time of high loop
voltage. Magnetic fluctuations are observed at the beginning
of the current quench during the disruptions. The generated
runaway electron (RE) current is larger at a lower level of
magnetic fluctuation. Experimental evidence supporting that
the theory of hot tail RE generation might be playing a role
has also been found. With higher temperature before the
disruption, more REs are generated via the hot tail
mechanism during the thermal quench. By increasing the hot
tail RE generation by increasing the temperature, an obvious
RE plateau is observed even with a low toroidal magnetic
field (1.2 T).},
