High-resolution x-ray imaging of K? volume radiation induced by high-intensity laser pulse interaction with a copper target

Popis výsledku v původním jazyce

In a proof of principle experiment using the LULI 100-TW laser facility ELFIE, we have demonstrated high spectral and spatial resolution of K? volume radiation induced by energetic electrons generated by irradiating solid Cu targets with visible (0.53 ?m) 350 fs laser pulses. Employing an x-ray spectrometer equipped with the spherically bent crystal of quartz (502) and with an image plate, single shot Cu-K? radiation was recorded in first-order reflection allowing for a geometrical mapping of the emission induced by hot electrons with a spatial resolution down to 30 ?m. The simultaneously achieved high spectral resolution permitted the identification of asymmetries in the K?1-group emission profile. Data from the shot in which a part of the laser beamwas incident at grazing angle to the target surface show a signature of enhanced lateral transport of energetic electrons.
