“…An electron (or positron) beam injected with the right phase can be accelerated by those fields to high energy in a much shorter distance than is possible in conventional particle accelerators. High quality electron beams of energy up-to 1 GeV have been produced in just a few centimeters [4][5][6][7], with 10 GeV stages being planned as modules of a high energy collider [8]. The efficiency and quality of the acceleration is governed by several factors which require precise three-dimensional shaping of the plasma column, as well as the laser and particle beams, and understanding of their evolution.…”

“…Therefore, laser-plasma accelerators are actively being investigated as ultra-compact sources of high-brightness beams for the next generation of light sources 2-4 and linear colliders. 5,6 High-quality electron beams up to 1 GeV have been experimentally demonstrated in cm-scale plasma channels. [7][8][9] The energy gain of a beam in the laser-driven plasma wave can be limited by several laser-plasma and beam-plasma interaction lengths.…”

Tapered plasma channels are considered for controlling dephasing of a beam with respect to a plasma wave driven by a weakly-relativistic, short-pulse laser. Tapering allows for enhanced energy gain in a single laserplasma accelerator stage. Expressions are derived for the taper, or longitudinal plasma density variation, required to maintain a beam at a constant phase in the longitudinal and/or transverse fields of the plasma wave. In a plasma channel, the phase velocities of the longitudinal and transverse fields differ, and, hence, the required tapering differs. The length over which the tapered plasma density becomes singular is calculated. Linear plasma tapering as well as discontinuous plasma tapering, which moves beams to adjacent plasma wave buckets, are also considered. The energy gain of an accelerated electron in a tapered laser-plasma accelerator is calculated and the laser pulse length to optimize the energy gain is determined.

“…Since then, efforts have focused on obtaining beams useful for high-energy particle colliders [7] and radiation sources [8][9][10][11]. This involves developing longer acceleration stages to achieve greater total energy gain, and controlling the injection process for higher beam quality.…”
