Error Analysis and RF Optimization of a Compact RFQ

A 162.5 MHz, 7.2 MeV 4-rod radio frequency quadru-ples (RFQ) dynamics design has been finished for injec-tor of a carbon ion cancer therapy facility which is pro-moted by the Institution of Modern Physics (IMP) of the Chinese Academy of Science (CAS). A detailed error analysis was performed after the optimization process. Field flatness error is analysed for determining a RF optimization target. The RF structure is designed based on a new type dynamics design. Electric field of the RF structure is optimized in order to supporting the dynam-ics design. The error analysis and detailed field flatness optimization of this compact RFQ have been presented and discussed in this paper.
