In order to draw a high-quality single-bounce capillary (SBC) to meet various applications, there is an increasing demand for detailed simulations of the SBC. In this study, a code based on the ray-tracing method was developed to simulate SBCs in detail for various X-ray sources to optimize their performances by considering factors such as attenuation of X-rays, coating, X-ray source characteristics (spot-size, distribution of energy, and intensity), surface shape errors, centerline errors, surface roughness, and absorption edges of X-rays. This code has monochrome and polychrome modes which were usually used to simulate the monoenergetic and polyenergetic performances of the SBC.
