Gas jet disruption mitigation of locked mode plasmas using DPCS real-time detection and response

Gas jet disruption mitigation of locked mode plasmas using DPCS real-time detection and response. R. Granetz, D. Whyte, S. Angelini, S. Wolfe. DPCS real-time detection of VDEs and subsequent firing of the gas jet worked well. DPCS: no false positives, no misses, fast response
