The one-step method for graphene oxide (GO) simultaneous reduction and carboxylation via ultraviolet irradiation in the inert atmosphere has been reported. X-ray photoelectron spectroscopy (XPS) an...

This paper deals with the analysis of the possible use of magneto-inertial fusion (MIF) to create a neutron source. We consider the configuration of the target in the form of an axially symmetric m...

The compact torus/toroid (CT) as future fusion reactor is presented. The field reversed configuration (FRC) is alternative thermonuclear scheme with properties of compact tori as both open and closed systems. By plasma confinement method field reversed configuration is closed magnetic trap. Mathematical model of plasma core in the fusion reactor is shown. Power balance for the FRC confinement chamber is calculated. The formula for bremsstrahlung more accurate in the temperature range of advanced fuel is presented. D- 3 He- 6 Li fuel cycle is proposed and reactor schemes are discussed.

Field reversed configurations (FRC), 1,2,3 as mirror machines have been developed as simple plasma confinement systems. FRC formed by reversing of magnetic field and reconnection and sustained by plasma current. Several mirrors may be linked together with solenoids - tandem mirrors (TM), end losses in the axisymmetric tandem mirror are reduced by ambipolar trapping - ambipolar trap (AT). Power balance of deuterium - helium-3 (D- 3 He) plasma in a prolate FRC power plant is compared with the power balance for a central cell of D- 3 He tandem mirror reactor (ambipolar trap). Deuterium - tritium (D-T) ITER 4 , kinetically stabilized tandem mirror (KSTM)5 and D- 3 He FRC5 parameters are demonstrated.

Magnetic geometries like the field reversed configuration and spheromak are compact toroids, where plasma is enclosed in a linear external magnetic field geometry. To burn advanced fuels requires a high fusion power density compact system and a D- 3 He field reversed configuration will be considered here. Such innovative confinement concept together with remarkable advantages of compact system and advanced fuels, including direct energy conversion, full lifetime fusion core, fusion space propulsion, nonelectrical application of D- 3 He fusion energy and space resources including helium-3 fusion fuel is very attractive.

The high fusion power density resulting from high beta (the ratio of the plasma to magnetic energy density) and natural divertor make the field-reversed configuration (FRC) a prime candidate for fusion reactor other than tokamak, the so-called alternate concept. Brief review of the simple compact system with natural advantages and reactor potential is given. Theoretical and experimental results over the last seven years are discussed.
