Dynamic Focusing to Suppress Emittance Transfer in Crab-Crossing Flat Beam Collisions
Derong Xu, J Scott Berg, Michael M Blaskiewicz +8
Flat hadron beam collisions, though expected to enhance peak luminosity by about an order of magnitude, have not yet been demonstrated. Our study reveals a critical limitation: rea…
