Production and metrology of 5 [mu]m x-ray apertures for 100 keV diffraction studies in the diamond anvil cell

Microminiaturization of the diamond anvil tip is necessary in order to obtain multimegabar pressures. Because of this and the steep pressure gradients present tiny x-ray beams are required. This paper describes the production and metrology of 5 [mu]m x-ray apertures for x-ray diffraction studies to 100 keV in the diamond anvil cell. It is expected that this design will serve as the basis for 2 [mu]m apertures.
