Abstract :
The review of activity on the GOL-3 program is presented. The first part of the results is concerned with the experiments on the uniform plasma heating by a 100 kJ E-beam. Heating of the bulk plasma electrons up to 1 keV at 1015 cm-3 density is achieved. The second group of experiments deals with so-called "two-stage" dense plasma heating. The 1016-1017 cm-3 hydrogen bunches of 0.5-3 m length are produced by gas-puffing. High efficiency of the conversion of the energy, delivered by E-beam to 1015 cm-3 background plasma occupying the rest of the device, to the dense plasma bunches, is demonstrated. Last part of the paper describes activity on the microsecond ribbon E-beam of 4×140 cm2 cross section and of 200 kJ energy content on the U-2 generator. The transportation of such a beam at 2 m distance in a slit vacuum channel and its shape transformation to a circular one is achieved.
