Encyclopedia > Beam emittance

The beam emittance of a particle accelerator is the amount of spread of the beam as it travels. A low emittance particle beam is a beam which does not spread. In early particle accelerators a Cockcroft-Walton voltage multiplier was responsible for voltage multiplying. ...


Ways of reducing the beam emittance include radiation damping.

Main Injector (2123 words)
It is essential to monitor emittance evolution of the beams in the Main Injector before transfer to the Tevatron in real-time.
Luminosity is a very strong function of the beam emittance and as such, it is very essential to monitor and maintain low emittance and high brightness during the acceleration.
Emittance calculations are done on the acquired data, and the results are displayed together with intensity values in a table.
