Argonne In-flight Radioactive Ion Separator

Expansion of the ATLAS radioactive beam program through a dedicated mass separator including a magnetic chicane, an RF sweeper, and a buncher/rebuncher resonator, is under development. The device, AIRIS, will allow for improved transmission of radioactive beams produced in-flight providing access to new regions of secondary beams both higher in mass and further from stabilitiy than previously possible at ATLAS. Additionally, short-lived in-flight beams will be available for all experimental target areas including those that are currently accesible, the SPS and HELIOS, as well as newly available areas such as Gammasphere, FMA, Gretina, and multi-purpose beam lines.
