The Prometheus proton therapy complex is a scalable serial medical facility dedicated to proton therapy. In addition to its clinical applications, the facility also enables research in such fields as radiobiology, medical physics, and materials science. This work provides a brief overview of the key fields of research and results achieved using this facility. The experience with this complex demonstrates its effectiveness in establishing centers for collective use, capable of addressing a broad range of clinical, fundamental, and interdisciplinary scientific challenges.
