The seminar title is "Radiolysis in the FRIB Beam Dump."
When exotic, secondary beams are produced at the Facility for Rare Isotopes (FRIB), a majority of the primary beam will remain unused and will be stopped in a water-traversed, spinning drum of Ti64 alloy. With the dissipation of such large amounts of energy, a plethora of valuable radionuclides is formed. Exploratory research with the heavy ion beams from the NSCL (National Superconducting Cyclotron Laboratory) demonstrated the feasibility of a synergistic collection, and the process has become colloquially termed â€˜isotope harvestingâ€(TM). However, next to nuclear, also radiolysis reactions are induced. The thereby created molecular radiolytic products, such as hydrogen peroxide, molecular hydrogen and oxygen, exhibit sufficiently long life times to allow an accumulation. In order to ensure adequate water conditions for isotope harvesting, knowledge about the behavior of these species is vital.
