Photographs of the sample environment within the polycarbonate enclosure used for tender X-ray experiments; the polypropylene window was removed for clarity. (a) View of the breadboard adaptation of the sample environment designed for mounting samples of irregular shapes, in particular, allowing for samples of various thicknesses to be mounted simultaneously while maintaining a common analytical surface plane. The breadboards can be arranged in a wide number of combinations. For scale, breadboard holes are spaced at 20 mm. (b) The same sample environment adapted to hold a single large sample, in this case a 600 mm section of rock core taken from the San Andreas Fault at Elizabeth Lake in Los Angeles County, California USA, at ∼300 m depth. In this case, the optimal solution was to use a piece of plywood with holes drilled in appropriate places to clamp the sample on. |
