About
Stefan Wackerow is a leading expert in laser-induced surface structuring, with a primary focus on mitigating electron multipacting in particle accelerators. His work centers on developing advanced laser systems to modify the internal surfaces of vacuum pipes, significantly reducing their Secondary Electron Yield (SEY). His most notable contribution is the design and demonstration of a picosecond pulsed 532 nm laser system capable of roughening and treating the inner surfaces of tubes up to 15 meters long—a breakthrough for large-scale accelerator infrastructure. This technique suppresses electron multiplication by creating rough surface textures that scatter secondary electrons, directly addressing a critical challenge in high-energy physics. His 2023 paper on this system has already garnered attention, laying the groundwork for more efficient and reliable particle accelerators. Wackerow’s innovative approach not only enhances accelerator performance but also opens new possibilities for surface engineering in confined geometries. His work stands as a vital step toward improving the longevity and stability of next-generation scientific instruments.
