The beams of 7 GeV electrons and 4 GeV positrons collide at the interaction point (IP) with the crossing angle of 83 mrad, and both beams are squeezed to 50 nano-m in the vertical direction and 10 micro-m in the horizontal direction at IP by the superconducting magnet system. The system consists of 8 superconducting quadrupole magnets (quadrupole doublets), 4 superconducting solenoids and 43 superconducting corrector magnets. After the installation of the magnet system into the beam interaction region, SuperKEKB was operated as the Phase-2 beam commissioning from 2018 March to 2018 July. In the paper, we would like to describe the superconducting magnet system and the experiences on the magnet system during the beam operation. PB - JACoW Publishing CP - Geneva, Switzerland ER -
