The main aim of the present study was to identify the fast neutrons irradiation fluence threshold, ϕth, at which the high-field critical current at low temperatures, Ic (10 K, 8 T), starts degrading. Following up on our previous publication for low irradiation fluences, two new irradiation steps were added. Up to the last but one irradiation step, the Tc in all samples followed a linear dependence on the fast neutrons irradiation fluence, Tc(ϕ) ≈ Tc(0) − τϕ (τ being a numerical constant in units of K/1022 m−2 and ϕ in 1022 m−2). In parallel, Ic (10 K, 8 T)continuously grew with ϕ up to the threshold fluence, ϕth ≈ 3× to 4.3 × 1022 m−2. The last gradual irradiation by ϕ ≈ 1.83 × 1022 m−2 brought a severe degradation both in Tc and Ic (10 K, 8 T) in most samples, irrespective of their irradiation history.
