Abstract: | The progress of the Separated Function RFQ(SFRFQ)accelerator,which can raise the field gradient of acceleration while maintaining the transverse focusing power sufficient for high current beam,is presented.In order to demonstrate the feasibilities of the novel accelerator,a prototype cavity was designed and constructed.Correspondingly,a code SFRFQCODEV 1.0 was developed specially for cavity design and beam dynamics simulation.The prototype cavity will be verified as a post-accelerator for ISR RFQ-1000 (Integral Split Ring RFQ)and accelerate O+ from 1 MeV to 1.6 MeV.To inject a higher current oxygen beam for the prototype cavity,the beam current of ISR RFQ-1000 was upgraded to 2 mA.The status of high power and beam test preparation for the prototype cavity are presented in this paper. |
