A radio-frequency quadrupole ( RFQ ) beam cooler is a device for particle beam cooling , especially suited for ion beams . It lowers the temperature of a particle beam by reducing its energy dispersion and emittance , effectively increasing its brightness ( brilliance ). The prevalent mechanism for cooling in this case... | https://en.wikipedia.org/wiki/RFQ_beam_cooler |
An RF antenna ion source (or radio frequency antenna ion source) is an internal multi- cusp design that can produce a particle beam of about ~30 to 40 mA current. It is used in high energy particle physics and in accelerator laboratories.
