Abstract

Systems operating under vacuum conditions in the presence of alternating magnetic fields such as particle accelerators are susceptible to electron clouds thus limiting their performance. In the Large Hadron Collider (LHC), electron clouds are a consequence of a material with an undesired inherent secondary electron yield (SEY) in proximity to the beam path. In order to mitigate electron clouds, Laser Engineered Surface Structuring (LESS) can be used [1]. Although, the theoretical background regarding these structures is not fully understood and there isn't a complete model which can predict the energy-dependent SEY corresponding to these structures [2].
