Résumé

We report on the characterization of recently developed submillimetric He gas jets with peak density higher than 10 ²¹ atoms/cm ³ from cylindrical and slightly conical nozzles of throat diameter of less than 400 m. Helium gas at pressure 300-400 bar has been developed for this purpose to compensate the nozzle throat diameter reduction that affects the output mass flow rate. The fast-switching electro-valve enables to operate the jet safely for multi-stage vacuum pump assembly. Such gaseous thin targets are particularly suitable for laser-plasma interaction studies in the unexplored near-critical regime.
