Two 90-mm Niobium-titanium (NbTi) double-aperture quadrupole magnets, also called MQYY in the LHC vernacular, have been developed and manufactured by the companies Elytt Energy and SigmaPhi under the QUACO project for the High-Luminosity LHC upgrades.

An overview of the results from a recent study of two different types of Nb3Sn wires by HyperTech Inc. (US) and Bochvar Institute (RU) at the University of Technology and Atominstitut in Vienna.

In a recent paper, the densification of coated Nb films on copper samples at 90deg angle of incidence was explored for different techniques.
