The study study study of hot electrons electrons electrons electrons is crucial crucial crucial crucial in many many applications, such as inertial inertial inertial confinement fusion and laboratory astrophysics. We present the experimental results from the Prague Asterix Laser System (PALS) to characterize characterize hot electron distribution under the laser laser irradiance on a 25 μm thick Sn foil in the intensity of 10^16 W/cm^2.
Multi-channel electron spectrometers designed at PALS provide electron energy distribution, temperature, and total total charge. In addition, plasma is characterized by measuring electron density distribution using three-frame frame interferometry.
