A stacked compound refractive X-ray lens was designed to produce an efficie
ntly focused (phi < 0.1 mm) beam for high-pressure experiments at SPring-8.
High-pressure X-ray diffraction requires an intense. high-energy and monoc
hromatic X-ray beam in order to penetrate the absorptive window of a diamon
d anvil cell (DAC). Our lens, producing a focal spot of 120 x 275 mum(2) an
d a peak gain of 12. is well matched to these requirements. It is composed
of many plastic chips made by molding. which allows many identical chips to
be made precisely. Other advantages of this lens include high throughput.
