Comprehensive diagnostics of hot electron emission from plasmas produced by sub-nanosecond terawatt laser on thin foil metal targets

Popis výsledku v původním jazyce

Interaction of high-power and high-energy lasers with matter generates plasmas emitting considerable amounts of relativistic electrons. In this contribution such plasmas were produced by PALS kJ laser facility delivering the beam with intensity of the order of 3 x 1016 W · cm−2 in 400 ps on thin foil metal targets. To study the emission of hot electrons in horizontal plane around the target, an array of electron spectrometers was employed. For experimental determination of the total number of hot electrons a target probe was used in order to measure the target current which neutralizes the positive target charge produced by these escaping hot electrons. Together with this diagnostics the femtosecond interferometry was used to obtain spatial electron density profiles in close proximity to the irradiated target at selected time delays. The number of electrons correlates with the flux of soft x-ray radiation observed with the use of an x-ray streak camera.n
