We found that the irreversible field of the c-axis oriented superconducting Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10+{delta}} (Bi-2223) tapes irradiated with 5.8 GeV Pb ions collapsed at temperatures approximately 75{percent} of T{sub c} regardless of fluence. This result may indicate an ultimate limit for the field application of Bi-2223/Ag tapes at liquid nitrogen temperature (77 K), since the columnar defects produced by heavy ions are the most efficient pinning centers known so far for the flux lines in a layered superconducting system. {copyright} {ital 1997 American Institute of Physics.}
