Electron cloud in accelerators

R Cimino, T Demma - International Journal of Modern Physics A, 2014 - World Scientific
Low energy electrons in accelerators are known to interact with the circulating beam, giving
rise to the formation of a so-called e-cloud. Such e-cloud may induce detrimental effects on …
