Electron storage rings can exceed brightness limits using interleaved bunch injection and ejection. This method enables higher currents for producing diffraction-limited soft X-ray photons, optimizing synchrotron radiation facilities.
Area of Science:
- Physics
- Accelerator Physics
- Materials Science
Background:
- Synchrotron radiation (SR) brightness is typically limited by electron beam emittance in storage rings.
- Achieving higher photon brightness is crucial for advanced scientific applications.
Purpose of the Study:
- To demonstrate a method for overcoming the emittance limit in electron storage rings.
- To enable the production of higher flux, diffraction-limited soft X-ray photons.
Main Methods:
- Utilizing interleaved injection and ejection of electron bunches from a high-repetition-rate source (>1 kHz).
- Employing short kicker pulse lengths to achieve high effective currents in ~1 GeV rings.
Main Results:
- The proposed method effectively overcomes the equilibrium beam emittance limitation.
- Significant flux of diffraction-limited soft X-ray photons can be delivered.
Conclusions:
- Existing SR facilities can be adapted for nonequilibrium operation.
- The technique allows for the construction of smaller SR rings compared to traditional storage rings.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
