Abstract
Based on the study of Integral Split Ring (ISR) RFQ structure, two 26 MHz heavy ion RFQ’s (ISR-300 and ISR-1000) have been built at Peking University for ion implantation. The ISR-1000 is a 1 MeV 2.6 meter long RFQ and needs only 25kW peak rf power input. To study the simultaneous acceleration, O + and O ions have been accelerated simultaneously in the RFQ’s. It shows that the simultaneous acceleration with different species and ratio of positive and negative ions in a RFQ will benefit the implantation. To increase accelerating efficiency of RFQ at its higher energy region, the feasibility of Separated Function RFQ (SFRFQ) is explored . In addition, a cavity section of 4 vane proton RFQ with 352 MHz and with the length of 1.18 m is constructed for experimental and technological studies.
