Title: Acoustic emission data from the MFTF magnets

Abstract

An acoustic emission (AE) technique for monitoring mechanical disturbances in large superconducting magnets was applied during testing of the MFTF yin-yang coils. A signal processing method was developed to locate sources of AE in the magnet and distinguish the type of activity. The method was then used to provide information on conductor motion activity and structural integrity of the magnet.
