Current Loop Decay in Rutherford-Type Cables
Recent measurements of superconducting particle accelerator magnets made of multistrand Rutherford-type cable have shown that the magnetic field and its main harmonics oscillate along the magnet axis with a wavelength nearly equal to the cable transposition pitch length.1,2 It was also observed that, at low transport current, the periodic magnetic field patterns can persist without any significant decay for more than 12 hours.1
