Experimental results from copper cones irradiated with ultra-intense laser light are presented. Spatial images and total yields of Cu K α fluorescence were measured as a function of the laser focusing properties. The fluorescence emission extends into the cone approximately 300 µm from the cone tip and cannot be explained by ray tracing including cone wall absorption. In addition the total fluorescence yield from cones is an order of magnitude higher than for equivalent mass foil targets.
