A 4-Rod RFQ with a frequency of 325 MHz and an output energy of 3 MeV will be build as a part of the FAIR project of GSI. Design studies and model measurements on a short prototype of a 325 MHz 4-Rod RFQ model were made including simulations using CST Microwave Studio. The latest simulation results regarding the dipole field of this structure are presented in this paper.

For the optimization of Radio Frequency Quadrupole (RFQ) design parameters, a certain voltage distribution along the electrodes of an RFQ is assumed. Therefore an accurate tuning of the voltage distribution is very important for the beam dynamic properties of an RFQ. A variation can lead to particle losses and reduced beam quality. Our electrode design usually implies a constant longitudinal voltage distribution. For its adjustment tuning plates are used between the stems of the 4-Rod RFQ. Their optimal positions can be found by an iterative process. To structure this tuning process simulations with a NI LabVIEW based Tuning Software and CST Microwave ® are performed and compared to measurements of the ReA3-RFQ of the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University. The results of this studies are presented in this paper.
