Description
Staging of Laser Plasma Accelerators (LPAs) towards high charge, high energy electron beams requires a stable first stage providing low energy spread beams for subsequent transport and acceleration. To ensure high capture efficiency in the second stage, the electron beam is imaged by an active plasma lens. High capture efficiency requires the beam’s energy spread to remain sufficiently low (<5%) to reduce chromatic focusing effects during transport which lead to an increase in spot size at the second stage. This talk will cover the status of the first stage of the staged accelerator at the BELLA PW facility. This includes reliable day to day performance of low-energy spread GeV beams, dependence of beam parameters with laser fluctuations, and status of laser stabilization systems.
