Abstract :
As an injector for the Separated Function RFQ (SFRFQ) accelerator, the Integral Split Ring Radio Frequency Quadrupole (ISR RFQ) accelerator was upgraded to achieve a higher beam current. The experiments on the RFQ accelerator indicated that the maximum accelerated O+ beam current could exceed 3.2 mA with an energy of 1.03 MeV and energy spread (FWHM) of 3.1%. The resultant beam is then transported through a 1-m-long magnetic triplet and finally accelerated to 1.654 MeV by the SFRFQ cavity. The beam conditions of the RFQ accelerator were carefully optimized to satisfy the requirements of the SFRFQ accelerator, and the combined accelerator was able to deliver 0.53 mA of O+ beam to the end of the beam line, which has sufficiently demonstrated the feasibility of the SFRFQ cavity.
