Abstract

In the first phase of the R&D programme for LHC dipoles, seven 10-m-long, 50-mm-aperture prototypes have been manufactured by European Industries. The first two prototypes, fabricated under a CERN-INFN Collaboration, were successfully tested in 1994. This paper provides a first assessment of the main test results of these two magnets, in particular for what concerns kinematics and evolution of the stress distribution in the magnet during cooldown, energization and warmup. The influence of some adopted technological solutions is also discussed. Based on test results, some design corrections are proposed for adoption in the design of the future 15-m-long LHC dipole prototype
