摘要: Future accelerator magnets will need to reach a magnetic field in the 20 T range. Reaching such is challenge only reachable using high temperature superconductor (HTS) material. The current densities and stress levels needed satisfy design criterion of make YBaCuO most appropriate candidate especially when produced IBAD route. HFM EUCARD program aimed at designing manufacturing dipole insert made HTS material generating 6 inside Nb3Sn 13 4.2 K. In insert, engineering higher than 250 MA/m2 under 19 are required performances. level consequently very high. protection also critical issue as shows low quench propagation velocity. coupling with makes problem even more difficult. mechanical designs be presented well technological developments underway realize this compact insert.
