摘要

Two detection methods based solely on sound and electromagnetic emissions form the arc are presented. Detection of arc induced sound signals 40 to 50 dB above background noise are observed. Detection of arc induced low radio frequency (HF) electromagnetic noise levels 20 to 60 dB above background are observed. The arc noise is randomly strongest on side A and/or B of the DIII-D rf system. The sum of these sensors correlates with tripping due to an increase in the rf reflection coefficient. The sensors are resilient to ELMs and other plasma noise.
