Abstract
A radio frequency quadrupole (RFQ), which is a combination of the standard 4-vane and 4-rod designs, with a window or windows cut through mid-portions of the normally solid vanes. The windows decrease the resonant frequency, minimize undesirable mode coupling in the RFQ and result in a smaller and more easily tuned accelerator.
