Talbot-Lau interferometry (TLI) enables X-ray imaging in multiple contrasts, especially for low-Z materials, complementary to conventional absorption radiography. A novel microstructured array anode target (MAAT) source offers major advantages over the combination of an extended X-ray source coupled with an absorption grating (also known as the source grating), including more efficient use of source X-rays and a larger field of view, especially so in the case of Xray energies greater than 30 keV. Therefore, there is an increasing interest in optimizing performance of the MAAT X-ray source to achieve high energy TLI. With the Monte Carlo simulation, here we systematically evaluate the MAAT source parameters for TLI and report the optimal values for high X-ray energies. In particular, the spatial dependence of the Xray generating capability of the MAAT is studied with respect to the incidence angle of the electron beam to the normal of the MAAT target surface.
