Summary
The Siam Photon Source
Area of Science:
- Accelerator physics
- Synchrotron radiation technology
Background:
- The Siam Photon Source is Thailand's first synchrotron research facility.
- Designing a magnet lattice is crucial for storage ring performance.
Purpose of the Study:
- To design the magnet lattice for the Siam Photon Source.
- To evaluate the performance of the designed lattice.
Main Methods:
- Utilized a double-bend achromat lattice design.
- Incorporated fourfold symmetry with four straight sections.
- Analyzed emittance and dynamic aperture.
Main Results:
- Achieved an emittance of 72 pi nm rad.
- Emittance is 1.4 times the theoretical minimum for an eight-bending-magnet configuration.
- Observed a dynamic aperture significantly larger than the physical aperture.
Conclusions:
- The designed magnet lattice for the Siam Photon Source is effective.
- The lattice balances relaxed parameters with good performance.
- The large dynamic aperture ensures efficient electron beam storage.
