The resulting electron beams have stable energies of (17.4 +/- 1.1) MeV and an energy spread of (13.5 +/- 1.5) MeV (FWHM), which has been achieved by optimizing the properties of the supersonic gas jet target for the given laser system. Due to the availability of few-terawatt laser systems in many laboratories around the world these stable electron beams open possibilities for applications of this type of particle source. %G English %L hal-01719271 %U https://ensta-paris.hal.science/hal-01719271 %~ X %~ ENSTA %~ CNRS %~ X-LOA %~ X-DEP %~ X-DEP-PHYS %~ ENSTA_LOA %~ UNIV-PARIS-SACLAY %~ X-SACLAY %~ ENSTA-SACLAY %~ TEST3-HALCNRS
