The SIRIUS-P commercial reactor design produces 1000 MWe and is driven by 60 KrF laser beams. The chamber has an inner radius of 6.5 m and consists of a first wall fabricated from a carbon/carbon composite and a blanket made of SiC. The chamber is cooled by a flowing granular bed of solid ceramic material, TiO2 for the first wall and Li2O for the blanket. The overall tritium breeding ratio is 1...

Experimental study on the influence of fibre content on crack behaviour and propagation in synthetic-fibre reinforced beams has been reported in this paper. The tensile behaviour of metallic fibre concrete is evaluated in terms of residual flexural tensile strength values determined from the load-crack mouth opening displacement curve or load-deflection curve obtained by applying a centre-point...

Recently it has been shown that it is possible to achieve directional emission out of a subwavelength aperture in a periodically corrugated metallic thin film. We report on theoretical and experimental studies of a related phenomenon concerning light emitted from photonic crystal waveguides that are less than a wavelength wide. We find that the termination of the photonic crystal end facets and...

Transition rates were obtained from spectra for pure metallic samples of atomic number ranging from 22 to 27, measured with monochromatic incident X-ray beams from a synchrotron source. The experimental setup for this consisted of an energy dispersive spectrometer in a conventional 45–45 geometry, mounted in an evacuated chamber. Absorption, detector efficiency and multiple scattering were take...
