Electron-cloud effect : ウィキペディア英語版 | Electron-cloud effect The electron-cloud effect is a phenomenon that occurs in particle accelerators and reduces the quality of the particle beam. == Explanation ==
Electron clouds are created when accelerated charged particles disturb stray electrons already floating in the tube, and bounce or slingshot the electrons into the wall. These stray electrons can be photo-electrons from synchrotron radiation or electrons from ionized gas molecules. When an electron hits the wall, the wall emits more electrons due to secondary emission. These electrons in turn hit another wall, releasing more and more electrons into the accelerator chamber.
