Abstract Runaway electrons produced during minor disruptions, which are confirmed by the hard x-ray system and the runaway energy spectrum system, are observed by a soft x-ray camera on the HT-7 Tokamak. In this observation, the soft x-ray system can also provide the size information and the position information of the runaway electron current directly from the signal information on the chord. This observation implies that the soft x-ray system can provide the control system with the physical information of the runaway electron current on future devices to avoid electrons hitting the first wall.
