  The KEK injector Linac feeds beams to four rings. It is called J-Linac. SuperKEKB Main Rings are High-Energy-Ring (HER) and Low-Energy-Ring (LER). The Linac injects a 7.0 GeV electron beam to HER and a 4.0 GeV positron beam to LER. It also injects electron beams into two light source rings. We have successfully performed this simultaneous four-ring injection. We achieve this complex simultaneous injection by using two electron guns, a positron source with a flux concentrator, and pulsed magnets. In SuperKEKB phase 3 operation, 2.0 nC electron and 3.0 nC positron beam injections were achieved.
