Title: Real-time Motion Control and Data Acquisition System for Scanning X-ray Microscopy using Programmable Hardware
Presenter: Nobuhito Inami, High Energy Accelerator Research Organization (KEK)
Abstract: Scanning transmission x-ray microscopy (STXM) has many advantages over other microscopy techniques. The most prominent feature is the capability of chemical and magnetic imaging with a high spatial resolution of about 10 nm. STXM has been used recently in a variety of research fields toward the realization of a sustainable society such as photovoltaic cells, soil science, aerosols, and permanent magnets. Explore the development of a compact STXM system using NI CompactRIO. Precise control of the sample position and high-speed data acquisition were essential to the system's success. The sample position is monitored by a laser interferometer with sub nanometer resolution and feedback from the cRIO FPGA.
