Enhancing full-field TXM with low emittance synchrotron sources: Mono-capillary condenser shaker optimization.

This article focuses on optimizing the use of a mono-capillary condenser shaker in synchrotron radiation based full-field transmission hard x-ray microscopy (TXM) to enhance the field of view (FOV) and imaging quality. The study combines theoretical analysis, simulations, and experiments conducted at the Shanghai Synchrotron Radiation Facility (SSRF) BL18B beamline, demonstrating that appropriate control of the shaker's amplitude and frequency can nearly double the TXM's FOV and improve illumination uniformity. Experimental imaging of a star pattern and a 28-μm lithium-ion battery particle confirmed that the optimized shaker enables high-resolution, three-dimensional nano-imaging with improved edge clarity and uniformity compared to static illumination. The findings suggest that this shaker-based approach offers superior photon utilization and expanded FOV relative to other methods, supporting enhanced imaging performance for diverse scientific applications using low-emittance synchrotron sources.
