Magnetic field measurements in plasma of multiwire array on the Angara-5–1 facility

The paper presents an improved probe technique for measuring magnetic fields inside the imploding liner, designed on the Angara-5-1 facility. The results of researches of wire (W, Al) and fiber (kapron) arrays implosion obtained on the Angara-5-1 facility at 4MA are presented. For the first time the radial and axial distributions of the azimuthal magnetic field were measured in detail at the mass ablation phase during the implosion of such wire arrays. Radial current density distributions were calculated. The obtained data were compared with the data of streak camera and current and voltage measurements. Based on the obtained experimental results made an estimate of the plasma ablation intensity for the arrays made of various substances.
