Abstract
The Phase I beam commissioning of SuperKEKB has been conducted from February to June in the last year. The injector linac has successfully delivered the electron and positron beams to the SuperKEKB main ring. The linac beam studies and subsystem developments are also intensively going on together with the daily normal beam injection to both rings of the SuperKEKB and two light sources. Towards Phase II and III beam commissioning of SuperKEKB, one of key issues is a fine beam control with the new beam position monitor readout system, a positron capture system based on the flux concentrator, a pulsed quadrupole and steering magnets, and a low emittance photo-cathode rf electron source. In this paper, we report the control system status of SuperKEKB injector linac together with the commissioning result of Phase I. In addition, the improvement plant of injector control system is also mentioned.
