Abstract
In an effort to develop economical magnets for an upgrade of the LHC injector complex, CERN started in 2009 an R&D program on superconducting fast cycled magnets (FCM). The program has achieved its objective with the tests of the FCM dipole demonstrator, for which the construction was completed in March 2012. The demo dipole magnet targets a field range usually covered by resistive magnets (1.5-2 T) and aims at being continuously pulsed at 0.4 Hz. When compared to other magnets for similar application, the CERN FCM has a number of novel features. In this presentation we report on the origin of the program, the magnet construction, and the test results, focusing especially on the energy efficiency, on the viability of the novel features, and on the reliability of the magnet.
