Description
A 36.526 MHz coaxial-split RFQ(Radio Frequency Quadrupole) accelerator has been developed for cyclotron injection. The main advantage of this cavity is that it can overcome the problem of an excessively large transverse size of conventional RFQs at low frequency, which is beneficial for the axial injection of the cyclotron and reduces the influence on the cyclotron yoke magnet. This coaxial-split RFQ is designed to accelerate a 3.5 mA H₂⁺ beam from 20 keV to 70 keV in continuous wave operation. Due to the special structure of the coaxial-split RFQ, the dynamics and RF structural design of the cavity are mainly presented in this paper.
