The goal of this workshop was to: • Improve understanding of beam-dust interactions in particle accelerators, in particular, of dust-charging and release mechanisms. • Improve understanding of evolution of beam-dust interaction rate as a function of beam and other parameters. • Present modelling work on beam-dust interactions and their consequences. • Present research on dust issues in space applications. • Improve understanding of the behaviour of dust particles in accelerator hardware systems (Vacuum, RF, treated surfaces. . . ) and their consequences. • Improve understanding of mechanisms of dust migration into sensitive devices, such as high field gradient superconducting cavities, and ways to prevent this migration. • Identify synergies between particle-accelerator and space-research communities. • Define next research steps and possible collaborations. The workshop was held at CERN, Geneva, Switzerland, from June 13 to 15, 2023. All presentations given during the workshop can be found on the Indico website. In this report, we document the main conclusions and questions discussed during the workshop.</abstract> </record> </records> </xml>
