The high throughput x-ray micro-CT and long working distance x-ray nano-CT

Abstract The micro-CT and nano-CT endstation have been established at beamline 31A of the Taiwan Photon Source (TPS). The TPS 31A beamline is sourced by a wiggler with multiple beam modes: white beam, high-flux mono-beam, and high-resolution mono-beam modes. At TPS31A, we have developed a system comprising micro-CT (Projection X-ray Microscope, PXM) and nano CT (Transmission Xray Microscope, TXM). The micro-CT was opened in the second half of 2022, while the nano-CT is currently under commission. The primary design of the micro-scale CT prioritizes speed, enabling efficient processing of multiple samples. It is equipped with an automated sample pre-alignment and loading system to facilitate high-throughput sample handling. Conversely, the nano CT focuses on longer working distances to accommodate in-situ experiments, catering to diverse sample requirements.
