Investigation of the plasma column evolution and dynamics in the PW-7 plasma accelerator

In this paper the results of measurements azimuthal component distribution plasma column magnetic field in coaxial accelerator PW-7 are presented. Registration was performed by probe method. The objective work is to investigate dynamics and temporal evolution field. It has been revealed that using a dielectric (quartz) tube limiting column, escape charged particles from discharge onto walls vacuum chamber can be avoided. Through use tube, redistribution current led change shape signals. addition, velocity measured time front, passing between bottom electrode measuring system. Using rectangular screen composed ferromagnetic material provided shielding quasi-static fields jumper electrodes. These allowed investigating major peculiarities complex behavior column. main objectives investigations at facility include detailed analysis system operation, studying effects different scenarios on
