3D-modeling for the LANL-APT RFQ

摘要

An 8-m-long 4-vane radio frequency quadrupole (RFQ) has been proposed by LANL for use in high-current proton accelerators. This RFQ is made up of four 2-m-long coupled segments; the end regions and segment joints need full 3D modeling. In this paper, the strategies for piecewise treatment of the RFQ and results of the modeling are presented.
