Advances in MgB₂ applications for particle accelerators

Advances in applications of MgB₂ superconductor for particle accelerators are reviewed. The MgB₂ superconductor provides its unique features of much higher critical temperature and critical field than that of NbTi with a potential for the competitive cost for the production. It may contribute to expand superconducting technology applications with improved energy balance with hither temperature operation combined with conduction cooling technology. The recent advances in MgB₂ applications for particle accelerators and associated devices are overviewed in this paper. (author)
