AB - SuperKEKB is an electron-positroncollider, which aims to achieve a peak luminosity 40 times higher than that of KEKB by using the so-called 'nano-beam' scheme. A major upgrade to the Main Ring (MR) magnet system was needed to realize this scheme. The upgrade includes 1) new beam lines in the entire interaction region;2) replacement of the main dipole magnets in the positron ring; 3) a new layout of the wiggler sections in the positron ring, and newly added wiggler section in the electron ring, and; 4) sextupole magnets with tunable tilting tables to control the ratio of skew/normal sextupole components in the positron ring. More than 400 magnets were designed, fabricated, field-measured, installed in the tunnel and aligned in time for Phase 1 commissioning. Alignment of the MR magnets was challenging, since the survey network was destroyed by the Great East Japan Earthquake. Tunnel position changes during the magnet alignment work caused by construction of a new facilities building made the alignment work even more challenging. Construction of the MR magnet system and its first commissioning are reported.
