Abstract
Composite tapes of the superconductor Bi2Sr2CaCu2O8 on silver were irr adiated with energetic light ions (0.8 GeV protons), creating extended splayed tracks approximately 7 nm in diameter via fission of Bi nucle i. Magnetic hysteresis indicates large enhancements of persistent curr ents J, especially at high fields and temperatures, and substantial ex pansion of the irreversible regime. The technique may be suitable for large scale applications due to the long range (approximately half met er) of fast protons.
