Abstract：
A method based on the transverse particle motion equation is described for the calculation of beam acceptance for RFQ accelerators. The result is given for a four-vane type RFQ accelerator with specific structure parameters. The system acceptance for proton beam is 0.0153 cm·rad in x-x′ phase space, and 0.0114 cm·rad in y-y′ phase space. The method can also be applied for the calculation of acceptance for other RF accelerators with known structures and linear transverse electric fields.
