| Abstract | Introduction Recently the GOL-3 facility was upgraded to configuration with a long multimirror parts of the magnetic system. After the proposition a multimirror open trap [1] some small proof-ofprinciple experiments on confinement of plasma with rather low parameters (see review [2]) were carried out. Earlier the possibility of effective plasma heating by a high-power relativistic electron beam was demonstrated at the GOL-3 facility, the electron temperature of plasma was obtained up to 2-3 keV [3]. Therefore from the point of view of demonstration of thermonuclear prospects of multimirror traps is important to perform the experiments on confinement of plasma with high parameters. The experimental mode of the GOL-3 facility was selected so that the condition of longitudinal confinement of plasma was satisfied, namely the density of plasma is (1-3)x10 cm, that corresponds to temperature about 1 keV for a high effective confinement. In the performed series of experiments the main attention was focused on heating and confinement of ion component of plasma. Experimental conditions on the GOL-3 facility Multimirror trap GOL-3 is intended for studies of heating and confinement of a dense (10l0 cm) plasma [3]. The magnetic system of 17-m -length consists of coils for transport and compression of the electron beam, a 12-meter-long solenoid with ~4 m multimirror sections at the ends (Bmax/Bmin=5.2T/3.2T, 20 cells each) and exit plasma creation system. Initial plasma density with variable axial profile was formed by two pulse gas valves. The plasma heating is provided by a high-power electron beam (1 MeV, 30 kA, 8 μs, 120150 kJ). Macroscopical stability of beamplasma system was achieved by forming of the longitudinal net current with safety factor q> 2-3. Here we will discuss the experiments with initial deuterium distributions marked as 1,2,3 in Fig.1. 0 3 6 9 |
