About
Stephan Pfeiffer is a leading expert in laser-based surface engineering for particle accelerator applications, with a focus on mitigating detrimental electron cloud effects through advanced surface structuring. His most notable contribution is the development of a picosecond pulsed 532 nm laser system capable of roughening and reducing the secondary electron yield (SEY) of the inner surfaces of tubes up to 15 meters long—a critical innovation for suppressing electron multipacting in accelerator vacuum pipes. This work, published in 2023 and already garnering 3 citations, demonstrates how laser-induced surface scattering can dramatically lower SEY, directly addressing a key challenge in high-energy physics facilities. Pfeiffer’s research bridges ultrafast laser processing and vacuum technology, offering a scalable solution for improving beam stability and machine performance. His achievements highlight a rare combination of practical engineering and fundamental surface science, making his methods highly relevant for next-generation colliders and synchrotron light sources. For students and researchers, Pfeiffer’s work exemplifies how targeted laser-material interactions can solve complex operational problems in large-scale scientific infrastructure.
