Název v původním jazyce

Thomson parabola spectrometer for energetic ions emitted from sub-ns laser generated plasmas

Popis výsledku v původním jazyce

Laser-generated plasmas were obtained in high vacuum by irradiating micrometric thin films (Au, Au/Mylar, Mylar) with the PALS laser in Prague.Irradiation conditions enabled ions to be accelerated in forward direction with kinetic energies of the order of 2MeV/charge state.Protons above 2MeV were obtained in the direction orthogonal to the target surface in self-focusing conditions.Gold ions up to about 120MeV and 60+ charge state were detected.Ion collectors and semiconductor SiC detectors were employed in time-of-flight arrangement in order to measure the ion velocities as a function of the angle around the normal direction to the target surface. A Thomson parabola spectrometer (TPS) with a multi-channel-plate detector was used to separate the different ion contributions to the charge emission in single laser shots, and to get information on the ion charge states, energy and proton acceleration.TPS experimental spectra were compared with accurate TOSCA simulations of TPS parabolas
