Some results of experiments on obtaining high temperature plasma on laboratory model of plasma chamber "MAGO"

Experiments were conducted on the "CASCADE" electrophysical facility which was used as a source of impulse power for laboratory model of deuterium plasma chamber with a circular MHD nozzle (MAGO chamber). The modes of device\´s operations were investigated at various values of deuterium pressure in the chamber both with preliminary introduction of magnetic field in the plasma and without it. Depending on conditions of experiment the neutron radiation was generated at the front of increasing current, at its maximum or on a falling down branch of current. Though the experiments were conducted at low energies of plasma chamber powering (100-500 kJ), the stable generation of neutrons was observed. The length of neutron impulse achieved the value comparable to length of neutron radiation being obtained in experiments, in which explosive magnetic generators of multimegajoule energy scale are used (/spl sim/1 /spl mu/sec and more). It was defined the optimal deuterium pressure in the plasma chamber for the used operation modes of the device.
