Abstract - Hysteresis and coupling losses have been measured on different types of Nb3Sn multif i 1 ament superconductors at magnetic field cycles from zero up to 6 Tesla respectively at frequencies up to 100 Hz. Both types of losses depend strongly on the conditions of the diffusion heat treatment.

2.1 Nb 3 Sn Development from the 1960s to the 1970s. The very first commercial Nb 3 Sn composite conductor, which was used for accelerator magnet models in the period from the 1960s to the 1970s, was in the form of a flexible tape (also called a ribbon). A schematic of a Nb 3 Sn ribbon is shown in Fig. 2.1. Fig. 2.1.

Niobium has been the material of choice for SRF cavities for several decades due to its formability and superconducting properties. The accelerating gradient of niobium cavities is, however, rapidly approaching a theoretical limit. To achieve higher accelerating gradients a new material is needed that can sustain high fields.
