TUPAS052 | Radiation Environment at ISOL Target Station of Rare Isotope Facility | 1766 |

Next-generation exotic beam facilities will offer a number of approaches to produce rare isotopes far from stability. One of the approaches is the Isotope Online (ISOL) separation concept, that is, the isotope production by interactions of light ion beams with heavy nuclei of targets. A pre-conceptual design of an ISOL target station was done as part of the research and development work for the Rare Isotope Accelerator (RIA). This report summarizes the results of radiation simulations for the RIA ISOL target station. The above includes radiation effects such as: prompt doses around the target station and from neutron sky-shine; residual activation effects such as ground water, air, and component activation; life-time of target station components; and heating and cooling for target, beam dumps, and shielding. | ||

Carbon foils are widely used in charge-exchange injection in high intensity hadron accelerators. There are a variety of physics issues associated with the use of carbon foils, including stripping efficiency, energy deposition, foil lifetime (temperature rise, mechanical stress and buckling), multiple Coulomb scattering, large angle single Coulomb scattering, energy straggling and radiation activation. This paper will give a brief discussion of these issues based on the study of the Proton Driver and experience of the Fermilab Booster. Details can be found in Ref*.
