Nanodiamond targets for accelerator X-ray experiments

Abstract Results of fabrication of a nanodiamond target for accelerator X-ray experiments are reported. Nanodiamond film with dimensions 5 × 7 mm and thickness of 500 nm has been made of the high pressure high temperature nanodiamonds using a filtration method. The average crystallite size of primary nanodiamond particles varies around 100 nm. Source nanodiamonds and fabricated nanodiamond film were characterized using Raman spectroscopy, electron microscopy, and X-ray diffractometry. Preliminary results show that targets made of nanodiamonds are perspective in generating crystal-assisted radiation by the relativistic charged particles, such as parametric X-rays, diffracted transition radiation, diffracted Bremsstrahlung , etc.
