Bootstrap current control and the effects of the radial electric field in stellarators

Shaing, K.C.; Carreras, B.A.; Crume, E.C.; Dominguez, N.; … - 2008

The effects of the radial electric field E/sub r/ on the bootstrap current in ATF-type configurations are studied with the Drift Kinetic Equation Solver (DKES). It is found that there is a range of E/sub r/ values over which the bootstrap current does not depend on E/sub r/. The effects of E/sub...

EFFECTS OF DIRECT FLUORINATION ON SURFACE CONDUCTIVITY OF EPOXY RESIN INSULATORS

LIU, YAQIANG; LI, LIQIANG - In: Surface Review and Letters (SRL) 21 (2014) 06, pp. 1450084-1

Epoxy resin samples were surface fluorinated using a F2/N2 mixture at different temperatures of 25°C, 55°C, 75°C, and 95°C for the same time. Attenuated total reflection infrared (ATR-IR) analyses indicate substantial changes in surface chemical composition and structure by the...

Enhanced high-temperature thermoelectric properties of Ce- and Dy-doped ZnO for power generation

Park, K.; Hwang, H.K.; Seo, J.W.; Seo, W.-S. - In: Energy 54 (2013) C, pp. 139-145

The incorporation of CeO2 and Dy2O3 to ZnO leads to a marked increase in the electrical conductivity. The absolute values of the Seebeck coefficients of Zn1−xCexO and Zn1−xDyxO increase with CeO2 and Dy2O3 contents up to x = 0.003 and 0.005, respectively, and then decrease with further...
