“…Most synchrotron radiation (SR) passes through the wiggler antechambers and is trapped in the photon stops located at the end of each cell. A tungsten clearing electrode is deposited via thermal spray on the bottom of the chamber as the primary EC mitigation technique [120,121].…”

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 the accelerated beam quality and stability. Those effects have been observed in most accelerators of positively charged particles. A longstanding effort has been so far devoted to understand in detail the physical origin of such e − cloud, its build-up and its interaction with the circulating beam. We will first describe the origin and the basic features causing e − cloud formation in accelerators, then we review some of the theoretical work produced to simulate and analyze such phenomenon. In selected cases, theoretical expectations and experimental observations will be compared, to address the importance of benchmarking codes versus observations to reach the required predictive capability. To this scope, codes need realistic input parameters which correctly describe material and surface properties at the basis of such e − cloud formation and build-up. The experimental efforts, performed worldwide in many surface and material science laboratories, to measure such essential parameters will then be presented and critically reviewed. Finally, we will describe some of the e − cloud mitigation strategies adopted so far and draw some conclusions.

“…The mitigation worked as expected and the blowup became unnoticeable, at least for three-bucket spacing in the case of KEKB [51]. Besides the magnetic field, various mitigation techniques have been developed and tested at the B-factories, against the formation of the electron cloud, including antechambers [37], TiN or diamond-like carbon coatings, grooved surface pipes [38], and clearing electrodes [39]. Those techniques will be effective for future super B-factories and damping rings of linear colliders.…”
