In the last years studies have been performed on the influence of various elements of the 4-rod RFQ on its field distribution. In particular the tuning process of the 4-rod RFQ with its tuning plates has been optimized. These studies have been complemented with detailed simulations on the fringe fields at the end of the electrodes and the conformity of the fields along the structure as well as the influence of other tuning elements like the piston tuner. Based on the findings of this research a proposal for a field optimized 4-rod RFQ model has been developed and will be presented in this paper.
