Description
The FCC-ee may face significant challenges related to electron cloud effects. These effects are expected to be most pronounced in the Z configuration, due to the highest number of bunches, which leads to the smallest bunch spacing, which is a key parameter in the e-cloud formation process. A high electron density within the beam pipe can limit accelerator performance through several mechanisms, including transverse instabilities, emittance growth, particle losses, vacuum degradation, and increased heat loads on the vacuum chamber walls. During the design phase, the goal is to suppress these unwanted effects. Consequently, various effective mitigation techniques have been investigated to prevent e-cloud avalanche build-up and its detrimental consequences.
