A new multiplexed emitting system enables multiple beamlines to generate ultrashort, coherent extreme ultraviolet (EUV) and X-ray radiation using an energy recovery linac (ERL). This design maintains microbunching through bending magnets for advanced light source applications.
Area of Science:
- Physics
- Engineering
- Materials Science
Background:
- Producing ultrashort, coherent EUV and X-ray radiation is crucial for scientific research.
- Maintaining beam microbunching through bending magnets in energy recovery linacs (ERLs) presents a challenge for multi-beamline operation.
Purpose of the Study:
- To design a multiplexed emitting system for multi-beamline operation of coherent light sources.
- To demonstrate the feasibility of maintaining microbunching and beam quality in a system with multiple bending magnets.
Main Methods:
- Theoretical analysis and numerical simulations were employed to design and evaluate the system.
- The proposed system incorporates multi-bend achromats, matching sections, and radiators.
Main Results:
- Microbunching and beam quality were successfully maintained after four bending sections.
- Five radiation pulses at 13.5 nm with MW-level peak power were generated from a single electron beam.
- The system design facilitates simultaneous operation of multiple beamlines.
Conclusions:
- The designed multiplexed emitting system effectively supports multi-beamline operation for ERL-based coherent light sources.
- This approach overcomes previous limitations in beam manipulation for advanced radiation generation.
- The method shows significant potential for enhancing the utility of synchrotron-based light sources.
