Abstract：
Dipole field in an RFQ accelerator exerts beam a bending force and thus results in beam losses on the machine. Measures must be taken to diminish the influence of the dipole field. Dipole stabilizer rod was proposed to shift the dipole modes far from the working quadrupole mode. In our recent measurements on a cold model RFQ, we observed some new phenomena associated with the function of dipole stabilizer rods. In this paper we report our results and give an analysis on these results. A new idea of imbalance insertion of the dipole stabilizer rods is proposed for both shifting dipole mode and reducing the dipole components in an asymmetrical RFQ.
