Description
Laser–plasma acceleration experiments rely critically on advanced gas-target systems capable of delivering well-defined density profiles within a high-vacuum environment. The properties of the resulting particle beams and radiation are highly sensitive to the target’s density distribution, making precise control and characterization essential. In this contribution, we present the development of gas targets designed for a broad range of high-repetition-rate laser–plasma experiments driven by high-intensity, ultrashort laser pulses. Hydrodynamic simulations of neutral gas flow are employed to guide target design, followed by experimental characterization using interferometry combined with tomographic density reconstruction. To enhance interaction stability, the targets are optimized for continuous-flow operation. We investigate conical and slit-type supersonic nozzles as well as advanced multi-component nozzle assemblies. Novel extended-length nozzles and dual-stage target configurations are introduced. Additionally, we describe the design and implementation of a differential pumping system enabling stable operation of continuous-flow supersonic nozzles in a vacuum environment.
