Description
High energy resolution is crucial for state-of-the-art ARPES and soft X-ray spectroscopy, requiring sources with meV or sub-meV level spectral resolution. Existing FEL and synchrotron beamlines are limited by energy jitter, spectral broadening, or repetition-rate constraints. We are currently developing a compact 500 MeV, 10 MHz light-source scheme based on angular-dispersion induced microbunching (ADM). Start-to-end simulations, from injector through linac, ADM beamline and radiator to dump, show that the scheme can deliver 0.1-meV-level energy resolution while preserving transverse emittance, with RF phase and timing jitter kept within tolerances. This compact, high-repetition-rate, high-resolution source would enable routine sub-meV ARPES and time-resolved spectroscopy that are effectively inaccessible with current FEL and synchrotron facilities.
