Detailed simulation and characterization of double paraboloidal monocapillary for laboratory x-ray sources
Abstract A double-parabola monocapillary (DPM) was designed for laboratory x-ray sources, and its performance was evaluated through numerical simulations and experimental validation. A surface shape error model was developed to characterize the DPM surface profile, and ray-tracing methods were used to simulate key properties such as focal spot size, divergence, and transmission efficiency. The simulation results closely matched experimental measurements, validating the proposed model. This surface shape error simulation provides an efficient method for evaluating the impact of slope errors on DPM performance, offering insights for optimal design and precision manufacturing.
