Beam Energy Deposition from PS Booster and Production Rates of Selected Medical Radioisotopes in the CERN-MEDICIS Target

CERN-MEDICIS uses the scattered (ca. 90%) 1.4 GeV, 2 uA protons delivered by the PS Booster to the ISOLDE target, which would normally end up in the beam dump. After irradiation, the MEDICIS target is transported back to an offline isotope mass separator, where the produced isotopes are mass separated, and are then collected. The required medical radioisotopes are later chemically separated in the class A laboratory. The radioisotopes are transported to partner hospitals for processing and preparation for medical use, imaging or therapy. Production of the isotopes is affected by the designs of the ISOLDE and MEDICIS targets. The MEDICIS target unit is a configurable unit, allowing for variations in target material as well as ion source for the production of selected medical radioisotopes. The energy deposition on both targets is simulated using the Monte Carlo code FLUKA, along with the in-beam production of some medical isotopes of interest. Diffusion and effusion efficiencies are then applied to estimate their production.
