biostudies-literatureUnknown21(1)Spohr TElectron beam water treatment (EBWT) is a promising approach for remediating water contaminated with per- and polyfluoroalkyl substances (PFAS). In this study, we assess the feasibility of using a compact, high-average-power superconducting radio-frequency (SRF) photoinjector as a source for delivering the electron beam parameters required to initiate PFAS degradation. Our goals are twofold: first, to determine whether such a system can achieve the necessary dose and dose rate through sufficient beam energy and power; and second, to establish an experimental platform for investigating how different beam conditions affect degradation pathways. We envision a compact and mobile SRF-based accelerator that can be deployed at contamination hotspots - such as the former Berlin airport Tegel - offPloS onee0323581https://www.ebi.ac.uk/biostudies/studies/S-EPMC12803471biostudies-literatureCompact high power, medium energy electron accelerator for treatment of per- and polyfluoroalkyl contamination in water.PMC12803471Kamps TSpohr TAlberdi Esuain BLederer SDirsat MfalseCompact high power, medium energy electron accelerator for treatment of per- and polyfluoroalkyl contamination in water.Electron beam water treatment (EBWT) is a promising approach for remediating water contaminated with per- and polyfluoroalkyl substances (PFAS).
