Abstract
Radiofrequency quadrupoles (RFQs) are low-energy rf accelerator structures which can efficiently transport and accelerate high-current ion beams. For a wide range of applications, RFQs can be designed that, like all rf accelerators, have a fixed output energy per amu, that can be varied by independently phased postaccelerator cavities. An attractive new development is an RFQ structure with variable energy which is achieved by frequency variation. The status of the work on fixed- and variable-energy RFQ applications is presented.
期刊介绍：
Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
