| 释义 |
A radio-frequency quadrupole (RFQ) is a linear accelerator component[1] generally used at low beam energies, roughly 50keV to 3MeV. It is similar in concept to a quadrupole mass analyser but its purpose is to accelerate a single-species beam (rather than perform mass spectrometry on a multiple-species beam). The RFQ is a combined-function component that both accelerates and focuses the beam of charged particles. Invented by Soviet physicists I. M. Kapchinsky and Vladimir Teplyakov in 1970, the RFQ is used as an injector by major laboratories and industries throughout the world for radiofrequency linear accelerators.[2] References1. ^{{Cite web|url=http://epaper.kek.jp/e02/PAPERS/THPLE045.pdf|title= The ISIS neutron source RFQ}} 2. ^{{cite book |title= Theory and design of charged particle beams |last1= Reiser |first1= Martin |authorlink1= |editor1-last= |editor1-first= | editor1-link= |edition = 2nd |date= 2008 |publisher= Wiley-VCH |location= Weinheim |isbn= 9783527407415 |page=6 |url= https://books.google.com/books?id=eegK9Mqgpi4C}} External links
