Multi-beam ptychography (MBP) enables X-ray ptychography on larger samples without sacrificing resolution. This paper discusses MBP's challenges, including speed trade-offs, reconstruction quality compared to single-beam ptychography, the effects of detector dynamic range on probe numbers, and the impacts of vibrations and coherence. We base our findings on recent MBP experiments to identify key performance factors.
