摘要：

Power tests and magnetic measurements have been performed on various 1 m long LHC dipole model magnets. Single and twin aperture magnets were energised up to peak fields above 9 Tesla. Subjects studied are quench behaviour, improvements in the test facility, and losses in the superconductors. The field quality was measured with rotating coils immersed directly in the 1.8 K bath of the vertical cryostat. The design of these coils as well as the achieved measurement precision will be presented. Preliminary measurements of the persistent currents show an unexpected time dependent decay of the field harmonics.
