摘要：

The effects of neutron irradiation in dry tube (DT) and rotary rack (RR) facilities at PUSPATI TRIGA Reactor on the superconducting properties of (Bi1.6Pb0.4)Sr2Ca2Cu3O10 (Bi-2223) are reported. The samples were prepared via the co-precipitation method and exposed to neutron irradiation in both facilities for 0.25 h to 5 h with neutron flux 6.90 x 10(12) and 2.75 x 10(12) n cm(-2) s(-1), respectively. The structure, microstructure, radionuclide, electrical resistance, and AC susceptibility were determined. Energy-dispersive X-ray analysis revealed the presence of Zn and Po due to the neutron activation. Gamma spectroscopy analysis showed that neutron irradiation produced Sr-85 radionuclide. The electrical resistance showed onset temperature, Tc-onset of 118 K and transport critical current density, J(c-t) of 2.14 A cm(-2) at 50 K for the non-irradiated sample. AC susceptibility showed that the transition temperature, T-c chi ' was around 106 to 109 K and 105 to 109 K for samples irradiated in DT and RR facilities, respectively. The lower peak temperature, T-pL of the imaginary part of the susceptibility, chi '' varied from 88 to 97 K. Sample irradiated for 4 h with neutron fluence of 3.96 x 10(16) n cm(-2) in RR facility showed the highest J(c-t) (15.88 A cm(-2) at 50 K). Samples irradiated in RR showed higher J(c-t) compared with samples irradiated in DT facility. Neutron irradiation suppressed the transition temperature and Bi-2223 phase, but improved J(c-t) by more than six times in DT and seven times in RR facility. The optimal neutron fluence for neutron irradiation in Bi-2223 was between 2.48 x 10(16) and 3.96 x 10(16) n cm(-2).
