Disruptions are highly undesired events during tokamak plasma discharge, and now massive gas injection (MGI) is the most promising technique mitigating all negative consequences of a disruption. A fast disruption mitigation valve has been designed and tested for J-TEXT tokamak based on eddy-current repulsion mechanism. In order to get the key operating parameters of the valve such as voltage and gas pressure in real time and to realize remote automatic control, a control system on LabVIEW software platform based on hardwires of sensors, relays, Advantech industrial computer and NI-6221 data acquisition card has also been designed. The experimental test results show that the control system works well.
