Summary
The Soft X-ray Laser (SXL) project at MAX IV Laboratory details its free-electron laser (FEL) design for Phase 1. This design focuses on self-amplified spontaneous emission (SASE) for short pulses and includes plans for future upgrades.
Area of Science:
- X-ray science
- Laser physics
- Accelerator technology
Background:
- The MAX IV Laboratory is developing a Soft X-ray Laser (SXL) facility.
- The SXL FEL will be driven by the existing 3 GeV electron linac.
- The project is structured in phases, with Phase 1 focusing on core functionality.
Purpose of the Study:
- To present the design of the SXL free-electron laser (FEL).
- To outline the performance parameters based on user requirements.
- To detail the initial operational mode and potential upgrades.
Main Methods:
- Design and simulation of a free-electron laser.
- Utilizing a 3 GeV electron linac as the driver.
- Focusing on self-amplified spontaneous emission (SASE) and short pulse generation.
Main Results:
- Simulation results for high and low charge linac bunches with varying pulse durations.
- Demonstration of two-color/two-pulse mode operation.
- Exploration of power enhancement via tapering and advanced seeding schemes.
Conclusions:
- The SXL FEL Phase 1 design supports SASE operation with short pulses.
- The system is adaptable for advanced seeding schemes.
- Future upgrades are planned for enhanced capabilities.
