Abstract For the first time, experiments on DIII-D tokamak have demonstrated electron cyclotron current drive (ECCD) with more than double conventional efficiency by tailoring wave-particle interactions in velocity space using a novel ‘top launch’ geometry. Steering EC waves to propagate nearly parallel resonance drives efficiently 1) selective damping electrons higher v||, and 2) longer absorp...

The article presents the results of energy efficiency study and light quality LED illuminators (lamps) for general lighting, in particular colorimetric parameters, flux modulation photobiological safety. It is shown that two-base lamps with G13 base luminaires outdoor lighting have achieved class A++. E27 indoor fixtures diffusers a output 25–35% lower correspond to classes A+, A, B. Correlated...

Triple junction lnGaP/GaAs/Ge solar cells are highly current mismatched due to the excess current generating capability of the germanium subcell. This severe current mismatch invites new approaches for increasing performance beyond that of current triple junctions: Presented here are two approaches for improving the efficiency of III-V multi-junctions beyond that of current triple junction tech...
