Description
Laser-plasma acceleration experiments require the implementation of gas target technology (a system delivering specific gas with a pre-defined density profile inside a high-vacuum environment). The generated particle beams and radiation in these experiments strongly depend on the choice of optimal density profile formed in a gas target. Here we present the development of gas targets suitable for various laser-plasma experiments driven by high-intensity ultra-short laser pulses at high repetition rates. Hydrodynamic simulations of the neutral gas flow are implemented to design the targets. Then, the target characterization is performed by interferometric measurement and tomographic reconstruction of the density profile. To improve the stability of the interactions, the targets are optimized to work in a continuous flow operation regime. We investigate the conical and slit supersonic nozzles. These nozzles are tested with a differential pumping system. Then, the novel extended length nozzles and dual-stage target designs are presented.
