Description
Multi-stage coupling of two or more laser-plasma accelerators is as a key technology for future high-energy physics applications of plasma-based accelerators, including TeV-scale collders. Single laser-plasma accelerators stages have demonstrated accelerating gradients orders of magnitude beyond conventional RF technology, high beam quality, and acceleration to 10 GeV. However, scaling to collider-relevant energies requires the efficient coupling of multiple plasma stages with beam quality preservation and minimal charge loss.
Currently, demonstrations of staging have been limited to energy gains at the ~100 MeV level, with low charge transport between the stages (Steinke, Nature 2016). At the BELLA Center, multi-stage coupling of laser-plasma accelerators at the GeV level is being investigated. This talk will present an overview of recent progress towards high quality multi-stage coupling including stable, high quality injectors, active plasma lenses, and plasma mirrors.
