PHITS is a general-purpose radiation transport simulation code that has been developed mainly by JAEA in cooperation with domestic and foreign research institutes. PHITS can simulate various radiation behaviors in all kinds of materials, and has been used by more than 7,000 researchers and engineers in a wide range of fields, including science, engineering, and medicine. We released the latest version, PHITS 3.27, in March 2022. This version includes several valuable improvements such as ITSART, a track-structure mode for arbitrary materials, and availability of nuclear data libraries for deuterons, alpha particles, and photons. In this presentation, we will introduce the new improvements and their features.
