摘要：A beam dynamics design of 352.2 Mhz radio-frequency quadrupole(RFQ) of Turkish Accelerator Center(TAC) project which accelerates continuous wave(CW) proton beam with 30 m A current from 50 ke V to3 Me V kinetic energy has been performed in this study. Also, it includes error analysis of the RFQ, in which some fluctuations have been introduced to input beam parameters to see how the output beam parameters are affected, two-dimensional(2-D) and three-dimensional(3-D) electromagnetic structural design of the RFQ to obtain optimum cavity paramaters that agree with the ones of the beam dynamics. The beam dynamics and error analysis of the RFQ have been done by using ***. Electromagnetic design parameters have been obtained by using SUPERFISh for 2-D cavity geometry and CST Microwave Studio for 3-D cavity geometry.
