Beam loading analysis and control in standing wave cavities
Available online 14 September 2026
The interaction between a particle beam and the accelerating mode of a radiofrequency (RF) cavity cause beam loading, representing the beam-induced cavity fields. Beam loading leads to amplitude and...
Booster-based beam recycling for swap-out injection at the High Energy Photon Source
Available online 12 September 2026
Fourth-generation synchrotron light sources employ ultralow-emittance storage rings with stringent injection requirements. On-axis swap-out injection alleviates the dependence on storage-ring dynamic...
