In contrast to Ti alloyed bronze route Nb<sub>3</sub>Sn wires, where a maximum is observed at around 0.4 ×10<sup>22</sup> m<sup>-2</sup>, it was found that the maximum of (<i>J</i><sub>c</sub>/<i>J</i><sub>c0</sub>) versus φ<i>t</i> in the present ternary alloyed wires was still not reached. A comparison with an earlier study on bronze route wires at RTNS-II shows that the variations of <i>T</i><sub>c</sub> versus φ<i>t</i> and <i>J</i><sub>c</sub> versus φ<i>t</i> do not scale: a substantially higher <i>J</i><sub>c</sub> value is now observed for the same <i>T</i><sub>c</sub> value. The degree of atomic ordering being comparable, the shift of the maximum of <i>J</i><sub>c</sub>/<i>J</i><sub>c0</sub> with fluence is attributed to radiation induced “defect clusters.” Two observations are used for explaining the observed effect: (a) a shift of (<i>J</i><sub>c</sub>/<i>J</i><sub>c0</sub>)<sub>max</sub> toward higher fields, observed for binary bronze wires with higher Sn contents and (b) by calorimetry, the average of the <i>T</i><sub>c</sub> distribution in the filaments of RRP and PIT wires is found to occur at values up to 1.5 K higher than in bronze wires. The present data suggest that the effect of “defect clusters” is higher for wires with higher average Sn contents.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>calorimetry; critical current density (superconductivity); multifilamentary superconductors; neutron effects; niobium alloys; tin alloys; Nb<sub>3</sub>Sn; PIT wire filament; RRP wire filament; TRIGA reactor; ambient reactor temperature; atomic ordering degree; average Sn contents; binary alloyed wire; binary bronze wires; bronze route wires; calorimetry; defect cluster effect; fast neutron irradiation; radiation induced defect clusters; ternary alloyed wire; Inductors; Neutrons; Niobium-tin; Radiation effects; Superconducting magnets; Wires; Critical current density; Nb-Sn; neutron irradiation; superconducting materials;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Applied Superconductivity, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>1051-8223</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TASC.2012.2237492</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6403521</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=112406' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=112406</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
