High-throughput injection-acceleration of electron bunches from a linear accelerator to a laser wakefield accelerator

Great strides have been made in this area in recent two decades, making PBA a candidate for next-generation light sources and colliders, making PBA a favorite for next-generation light sources and colliders. A PBA will first demonstrate the injection and acceleration of beams first created using a conventional RF accelerator. Only a small amount of the injected charge was increased in some recent studies on LWFA staging and external injection-acceleration in PWFA. For future colliders where beam energy will need to be raised using multiple stages, the coupling effectiveness per stage must reach 100%. Here we trace the first demonstration of external injection from a photocathode-RF-gun-gun-based conventional linear accelerator to a LWFA and subsequent acceleration without loss of charge or degradation of quality, which is facilitated by properly shaping and matching the beam into the plasma structure.

First Simultaneous Acceleration of Multiple Charge States of Heavy Ion Beams in a Large-Scale Superconducting Linear Accelerator

The xenon beam intensity increased by 2. 5 percent in comparison to the single-charge-state beam as a result of the recombination of three charge states in the six-dimensional phase space. Lastly, the Letter's findings reveal that it is possible to produce and use high-quality multiple-state heavy-ion beams in a large-scale superconducting linac to raise the available beam power on a isotope production target.

Six-dimensional matching of intense beam with linear accelerating structure

Beam matching is a common technique that is routinely employed in accelerator design with the intention of minimizing beam losses and preservation of beam brightness. Despite being widely used, a complete theoretical study of beam matching in 6D remains elusive. We present an analytical investigation of 6D beam matching of a high-intensity beam onto an RF structure in this work. We begin our investigations within the framework of a linear model, and use the averaging technique to a set of 3D beam envelope equations.
