Abstract: We present the results of experimental investigation of ion and electron fluxes produced by irradiating thin foils with laser USPs. These experiments were carried out on the Sokol-P laser facility (pulse duration ~1 ps, power ~20 TW) using lavsan, aluminium, and copper targets of equal thickness (~5 mm). Ions were recorded employing Thomson spectrometers and a time-of-flight spectrometer with a silicon semiconductor detector. To record electrons, use was made of electron spectrometers involving the rotation of particle trajectories by 180° in magnetic field. The ionic composition of the charged particle beam was determined and the beam shape was investigated in relation to the target material.
