TL;DR: The High Luminosity (HiLumi) Large Hadron Collider (LHC) project has, as the main objective, to increase the LHC peak luminosity by a factor five and the integrated luminosity, which will be achieved mainly with a new interaction region layout which will allow a stronger focusing of the colliding beams as discussed by the authors.

TL;DR: In this article, the authors summarized the strategy and actions being undertaken in the framework of the FCC 16 T Magnet Technology Program and the Work Package 5 of the EuroCirCol.

TL;DR: In this paper, the authors summarized the activities and plans for the development of these magnets, in particular within the 16 T Magnet Technology Program, the WP5 of the EuroCirCol, and the U.S. Magnet Development Program.

TL;DR: Several development programs for these magnets, based on Nb3Sn technology, are being pursued in Europe and in the U.S. as mentioned in this paper summarizes and discusses the status, plans, and preliminary results of these programs.

TL;DR: In this article, a detailed visual inspection of the first generation coils was carried out to investigate cable dimensional changes during heat treatment and the position of the windings in the coil straight section and in the end region.
