SL-ALC
Your tool to control electron acceleration
The SL-ALC system
The SL-ALC-HI system is a motorized cell of adjustable length, conceived for laser-plasma interaction experiments at underdense regime, requiring mm-to-cm long stable medium in general (e– acceleration and diffraction, inverse Compton scattering, γ-ray generation, X-ray laser, high harmonic generation), and Laser Wakefield Acceleration (LWFA) at high repetition rate in particular.
High-precision monitoring
Fully motorized and easy to align
Optimal plasma imaging conditions
Pulsed and regulated pressure modes

Optimal plasma imaging conditions
Pulsed and regulated pressure modes
Unique instrument to fine-study with optical diagnostics the physics of laser-plasma interaction in underdense regime
This system is designed to offer perfectly reproducible laser-plasma interaction conditions. The solid and shielding metallic housing and specific in-out nozzle design enable very reproducible shots with a multi-Terawatt to Petawatt laser system without fatal damaging and dangerous light backscattering at normal laser incidence. The gas-tightness is tested for resisting up to few bars of flow pressure (approx. 1020 atoms/cm3 at normal temperature).
Typical electron spectra for different SL-ALC length configuration with a 40 TW laser system
Possible implementation for electron acceleration and plasma observation
