The results of experiments received on the plasma focus (PF) device with energy stored equal 4 kJ are represented. Photos of the current plasma sheath (CPS), pre-pinch, sphere-like plasma formations are produced with the help of the electron-optical converter contained a gated micro-channel plate (MCP) and the CCD-camera imaging system in the visible region. The redial velocity of the CPS is about 10⁷ cm/s. Neon plasma electron density measured with the help of the interferograms in the visible region and the spectrums in the soft X-ray region equals 3·10¹⁸ cm⁻³. Electron temperature equals about 200 eV. Discharge integral photos were obtained with the help of the soft X-ray pinhole camera. Pictures with 2 μs resolution of the plasma luminescence above PF anode region were made by CCD-camera.
