Abstract :
Acoustic emission (AE) from superconducting magnets has been analysed in terms of various AE parameters. From the analysis of irreversible and repeatable AE behavior it was confirmed that the flux motion is minor as the AE sources in the magnet. The mechanical disturbances caused by magnet quench were monitored by the use of coincidence method. Effectiveness of AE techniques for the AE location was also confirmed.
