Studying the Influence of fast neutron irradiation on properties of Bi2- Pb Sr2 Ca2 Cu3- Ni O superconducting system.

Evaluation of irradiation effects on the microstructure and properties of Ag-sheathed Bi-2212 superconducting round wire for future application in CFETR

“…It is well established that the shift of x-ray diffraction peaks can be primarily attributed to three main factors, including lattice parameter change, residual stress, and defect concentration [28][29][30]. The findings in the present work are similar to the reported results by [16], where the XRD diffraction peaks of Bi 2-x Pb x Sr 2 Ca 2 Cu 3-y Ni y O 2n+4+δ superconducting material shifted rightward to a higher angle after the fast neutron irradiation (5 MeV, 1.296 × 10 11 n cm −2 ). They explained that it was resulted from the lattice distortion with a deduced lattice parameter a from 5.4399 to 5.437 Å, mainly affected by the performed irradiation [31].…”

“…It is widely accepted that the current in the Bi-2212 round wire generally transports through the grain boundary and the a-b plane within the grain, while the current flow can be readily inhibited by the lattice distortion due to the presence of defects [15][16][17][18][19][20][21]. As demonstrated by the heavily disordered atomic arrangement in the irradiated sample (figures 6(b) and (d)), it can be briefly concluded that the irradiation defects could disrupt the connectivity of the Bi-2212 superconducting region, thereby resulting in the J C degradation of Bi-2212 round wire, consistent well with the previous reports [12,18,19].…”

“…Nevertheless, HTS is generally required to be exposed to different levels and types of irradiation. There were some previous studies to report the influences of ion irradiation [13][14][15], neutron irradiation [16,17], electron irradiation [18] or proton irradiation [19,20] on the microstructure and property of the Bi-2212 superconducting materials, mainly aiming to evaluate the applicability of the Bi-2212 as a strong magnet operated in an irradiation environment. Some investigations [11-14, 19, 20] have verified that the irradiation could lead to the creation of columnar pinning sites by the latent fission tracks, and thus the flux pinning effect could be enhanced by increasing irradiation defects.…”

Analyze the Structure and Electrical Properties of PbBr2 Ca1.9Sb0.1Cu3O8+ δ Superconducting Gamma Irradiation

“…These samples' -T (resistivity vs. temperature) properties were assessed using a conventional d.c. four-probe method to look into their superconducting condition. Other sources [14][15][16][17][18][19][20] have described how to measure the crucial temperatures. Structure was discovered through (XRD) measurements in the 20 to 50 range.…”

“…bringing to a close our earlier research on the impact of additions, such as Sr, La, Pb, Cr, Cd, Y, Sb, Ag, and O2, based on the chemical composition and electrical characteristics of superconducting material , crystallization constants and melting points, modified [1][2][3][4][5][6][7][8][9][10][11][12][13]. We will research the impact of gamma radiation on the structural and optical properties of the superconducting moreover the effect of the preparation circumstances on these properties [14][15][16]. Furthermore, irradiation can be used to study some of the characteristics of Bi2Sr2Ca2Cu3O10 [17].…”
