Design and numerical simulations of W-diamond transmission target for distributed x-ray sources
Distributed x-ray sources enable novel designs of x-ray imaging systems. However, the x-ray
power of such sources is limited by the focal spot power density of the fixed anode. To
further improve x-ray output, we have designed and evaluated a diamond-W transmission
target for multi-pixel x-ray sources. The target features a thin layer of tungsten deposited on
a diamond substrate. The thickness of tungsten layer was optimized for maximum fluence
through Monte Carlo simulations. Finite element thermal simulations were performed to …
