Transverse pressure dependence of the critical current in epoxy impregnated REBCO Roebel cables

The aim of this assignment was to find out whether impregnated REBCO Roebel cables can withstand the transverse stresses up to 150 MPa in an accelerator magnet. Before the stress test could be done, a suitable impregnation material and method had to be found, and the effect of out-of-plane bending needed to be determined. A new U-shaped sample holder for the press was constructed according to the measured bending properties. A REBCO Roebel cable was impregnated on this sample holder, and subjected to pressures up to 327 MPa.
