Query: Staging of High-Gradient Wakefield Accelerators   Accelerating particles to high energies with a high-gradient wakefield
accelerator may require use of multiple stages. Coupling beams from one stage
to another can be difficult due to high divergence and non-negligible energy
spreads. We review the challenges, technical requirements and currently
proposed methods for solving the staging problem.
