Critical current variation as a function of transverse stress of Bi-2212 Rutherford cables

PDF Version Also Available for Download.

Description

Transverse loading experiments on wire has shown that a significant drop in critical current occurs for stresses greater than 50 MPa. However, many high-energy physics applications require that the Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} conductor withstand stresses greater than 100 MPa without permanent degradation. Therefore, a study of epoxy impregnated cables, identical to those used in accelerator magnet applications, has been performed. This work presents the first results of Rutherford cables of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} with transverse stress. The results show that the cable can withstand stresses up to 60 MPa with a strain of about 0.3 % ... continued below
