Recent advances in hadron therapy have stimulated growing interest in the use of light, positron-emitting ion beams as an alternative to conventional heavy ions such as 12C. These radionuclides-produced efficiently through projectile fragmentation and in-flight separation-offer half-lives and production yields well suited for in-beam positron emission tomography (PET), enabling improved real-time verification of beam range during treatment. In this poster, a conceptual design for a fragment separator optimized to deliver such therapeutic positron-emitting light ions will be presented. The system integrates a production target with a sequence of dipole and quadrupole magnets, energy-loss degraders, and time-of-flight diagnostics to perform Bρ-Δ E-ToF particle identification and achieve high beam purity and tunability. This design provides a flexible platform capable of supplying a range of clinically relevant positron-emitting isotopes, supporting enhanced imaging-guided dose delivery and paving the way for more precise and adaptive cancer treatment modalities.
