Focussed ion beam (FIB) milling can be used to reveal sub-surface fracture and deformation below indents in materials. However, evolution of residual stresses around the indent impression cause changes to the crack morphology during the FIB cross-sectioning procedure. Berkovich nanoindents in single crystal hexagonal (6H) silicon carbide cause r…


Shutdown dose rate calculations provide an essential input to the design and research of fusion power plant technology. They allow the estimation of dose to personnel and equipment during planned and unplanned maintenance. The mesh coupled rigorous 2 step (MCR2S) methodology used at Culham Centre for Fusion Energy (CCFE) was originally developed to…

Ray-tracing techniques are applied to divertor filtered imaging, a diagnostic that has long been plagued by polluting reflected light features in metal walled fusion machines. A physically realistic surface reflection model is developed from a Cook-Torrence microfacet BRDF model. Camera calibration images of in-vessel point lights at JET are use…

The time evolution of edge localized modes ( ELMs ) in the Joint European Torus tokamak [ P. H. Rebut and et al. , Nucl. Fusion 25 , 1011 ( 1985 )] is investigated using the JETTO predictive modeling code [ M. Erba and et al. , Plasma Phys. Controlled Fusion 39 , 261 ( 1997 )] . It is found that both pressure-driven ballooning and current-driven pe…
