Abstract
We are developing a linac upgrade to increase the positron energy from the current 3.5 GeV to 8 GeV for SuperKEKB. For this project, we are considering replacement of the current S-band system for the last three sectors (24 subunits) by a C-band system with six sectors (48 subunits) utilizing the current infrastructure effectively. One unit of a high-power RF source and an accelerator system were newly introduced and processing of the C-band accelerator guide up to 43 MV/m was achieved. Thereafter, an accelerator was installed in the beamline of the KEKB linac to c onduct a beam acceleration test. Beam acceleration was successfully performed and the 43 MV/m acceleration gradient was confirmed. The C-band accelerator guide is now in operation in the KEKB linac. A brief description of this project and the current status of R&D are presented in this paper.
