Radioactive isotopes are used in solid-state physics to investigate the crystallographic, electric, and magnetic properties of nanostructures, usually via ion implantation. The CERN Apparatus for Surface Physics and Interfaces (ASPIC), which has been used since the 1980s to study metallic surfaces and thin films, has recently been updated to the new ASPIC Ion Implantation Chamber (ASCII). The ASCII system enables the implantation of radioactive ions at a range of energies, including ultra-low energies, and permits precise measurement of the depth of radioactive probe implantation. This ultra-high vacuum implantation chamber enhances experimental capabilities and permits the use of hyperfine techniques, making it an important tool for surface and interface research in solid-state physics.
