Invention Summary:
Scanning probe microscopy (SPM), a key invention in nanoscience, has now been extended to a wide spectrum of basic and applied fields. Its application to basic science led to a paradigm shift in understanding and perception of matter at its nanoscopic and even atomic levels. SPM uses a sharp tip, as a tool, to physically raster-scan samples and locally collect information from the surface. These measurements are typically performed under ultra-high vacuum (UHV) and controlled temperature conditions. In UHV systems, tools must be transferred from one site at room temperature to the other a low temperature or vice versa without breaking vacuum.
Researchers at Rutgers University have developed a novel, flexible, and space-efficient tool transfer system designed for SPM setups operating in cryogenic UHV with magnetic fields. It replaces bulky traditional vertical translation stages with a small footprint transfer mechanism that shuttles tools and scanning probes between two locations held at different temperatures without compromising the vacuum. Key features include (i) gravity-assisted tools that automatically engage and disengage with the SPM to transfer it between room temperature and cryogenic temperature sites; (ii) a terminal post used to trigger the tools and reset them to their starting state; (iii) a height lock mechanism to automatically lock the height of the tool during transfer; and (iv) a resilient fork-based tool stand which stores the transfer tool when not in use and enables control of the tool for transfers; These features overcome the limitations of bulky traditional translation stages, simplify the overall structure, and improve the reliability of the transfer process.
