Cover Picture

The very dense electron bunches of diffraction-limited storage rings could cause hardware damages if not properly handled. As shown in the open access article NUCL SCI TECH 32, 136 (2021), the electron bunches in the High Energy Photon Source (HEPS) storage ring are designed to be swap-outed and recycled in the booster, but could cause damages to the extraction Lambertson magnet in case of extraction kicker failures. To this end, a horizontal pre-kicker system is designed to kick the bunch once to trigger the decoherence and dilution prior to its extraction, as shown in this cover picture.

This scheme ensures safe extractions and highly eff cient transmissions in the swap-out & recycle process of HEPS, and is relevant for designs of other diffraction-limited storage rings. https://doi.org/10.1007/s41365-021-00974-z
