Electron cloud mitigation with laser ablated surface engineering technology

Parameters of the high intensity accelerators with positively charged beams could be compromised by electron cloud (e-cloud) effect. One of the most efficient mitigation method is providing the beam vacuum chamber walls with low secondary electron yield (SEY). A discovery of low SEY surfaces produced with laser bblated surface engineering (LASE) brought a new technological solution for e-cloud mitigation. This paper highlights the main results obtained since its discovery in 2014.
