Title :
Electron cloud in the Fermilab Booster
Author_Institution :
Fermilab, Batavia
Abstract :
Simulations of the Fermilab Booster reveal a substantial electron-cloud buildup both inside the unshielded combined-function magnets and the beam pipes joining the magnets, when the second-emission yield (SEY) is larger than ~ 1.6. The implication of the electron-cloud effects on space charge and collective instabilities of the beam is discussed.
