The study of hot electrons is crucial in many applications, such as inertial confinement fusion and laboratory astrophysics. We present the experimental results from the Prague Asterix Laser System (PALS) characterizing hot electron distribution of plasma generated on a 25 μm Sn foil irradiated by laser beam of intensity ൎ 10ଵ W/cmଶ.
Multi-channel electron spectrometers designed at PALS provide energy distribution, temperature, and total charge of generated hot electrons. In addition, plasma is characterized by measuring electron density distribution using three-frame interferometry.
The principles of electrons spectrometer and complex interferometry are also described.
