One way only to synchrotron light sources upgrade?

Area of Science:

• Accelerator physics
• Photon science
• X-ray technology

Background:

• Global trend to upgrade synchrotron light sources to diffraction-limited storage rings (DLSRs).
• DLSRs promise orders of magnitude increase in spectral brightness and transverse coherence.
• A key challenge is maintaining short photon pulse durations (<80 ps FWHM) for advanced experiments.

Purpose of the Study:

• To evaluate the compatibility of sub-picosecond photon pulse generation schemes with DLSRs.
• To assess these schemes against standard multi-bunch operation and diffraction-limited electron optics.
• To consider the impact of storage ring beam energy and existing infrastructure constraints.

Main Methods:

• Analysis of sub-picosecond pulse generation techniques in the context of DLSR parameters.
• Evaluation of compatibility with multi-bunch operation and electron optics.
• Consideration of synchrotron infrastructure limitations and beam energy.

Main Results:

• Compatibility of sub-picosecond pulse generation with DLSRs is discussed.
• The influence of beam energy and existing infrastructure on pulse generation is analyzed.
• An alternative scheme for upgrading medium-energy synchrotrons to DLSRs with picosecond pulses is presented.

Conclusions:

• Sub-picosecond pulse generation in DLSRs presents compatibility challenges with standard operations and optics.
• Existing infrastructure and beam energy are critical factors in scheme selection.
• A novel approach offers a pathway for upgrading medium-energy synchrotrons while enabling picosecond pulse generation.
