Abstract
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.
