Beam delivery and beamstrahlung considerations for ultra-high energy linear colliders Journal Article uri icon



  • Abstract; As part of the Snowmass'21 community planning excercise, the; Advanced Accelerator Concepts (AAC) community proposed future linear; colliders with center-of-mass energies up to 15 TeV and; luminosities up to 50 × 1034 cm-2 s-1 in a; compact footprint. In addition to being compact, these machines must; also be energy efficient. We identify two challenges that must be; addressed in the design of these machines. First, the Beam Delivery; System (BDS) must not add significant length to the accelerator; complex. Second, beam parameters must be chosen to mitigate; beamstrahlung effects and maximize the luminosity-per-power of the; machine. In this paper, we review advances in plasma lens technology; that will help to reduce the length of the BDS system and we detail; new Particle-in-Cell simulation studies that will provide insight; into beamstrahlung mitigation techniques. We apply our analysis to; both e; +; e; - and γγ colliders. The challenges and; solutions described in this paper are considered independently. A; unified, self-consistent concept for a BDS system for a 15 TeV; linear collider will be the subject of future work.
