H. Vormann et al., DESIGN OF LOW-FREQUENCY RFQ ACCELERATORS FOR ION-IMPLANTATION, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 113(1-4), 1996, pp. 38-41
The development of the 4-Rod RFQ as an injector for low charged heavy
ions has demonstrated that structures with spiral-shaped or straight s
tems can be made highly efficient, very stable, and compact. The desig
n of the RFQ structures and results of optimizations with respect to i
mpedance and field quality will be discussed.
