MS, Chemistry, University of Wisconsin-Madison, 2006 PhD, Nuclear Physics, University of Wisconsin- Madison, 2010 Joined NSCL in August 2016 severin@frib.msu.edu In my group we develop the equipment and techniques necessary to collect and use by-product radionuclides from NSCL and FRIB. The entire process is termed “isotope harvesting” and it has been identified by the U.S. Nuclear Science Advisory Committee as a promising new source for hard-to-produce radionuclides. Students in the group work on isolating individual elements from the mix of radionuclides that are present in gas, water, and solid metal matrices at the facility. As we start to collect isotopes with greater frequency, we will match them to basic and applied science research in fields like medicine, physiology, and nuclear security. Students in my group are immersed in a large variety of fields like nuclear physics and targetry; analytical, inorganic, and physical chemistry; and, depending on student interest, applied radionuclide research areas like radiopharmaceutical science, or nuclear security. Within that broad scope, students have the freedom to pursue the area of research that interests them to arbitrary depth. Students are funded by DOE sponsored research projects and fellowships and are expected to spend one semester doing practicum research at a DOE-run national lab. For the isotope harvesting project we built a new beam dump and water circulation system to allow us to collect isotopes at NSCL. The design was specifically aimed to replicate the FRIB water purification system so that our efforts now will be applicable for isotope harvesting at FRIB. As FRIB comes online we are also building a new radiochemistry laboratory where we will be able to process harvested isotopes and implement new purification and separation schemes for elements ranging from magnesium to protactinium.

BA, Physics, Coe College, 1980 MS, Physics, Michigan State University, 1982 PhD, Physics, Michigan State University, 1985 Joined NSCL in January 1985 sherrill@nscl.msu.edu Approximately 270 isotopes are found naturally. However, many more isotopes, nearly 7,000 in total, can be produced by particle accelerators or in nuclear reactors. These isotopes are radioactive and spontaneously decay to more stable forms, and I work to produce and separate new and interesting ones. There are several reasons why a latent demand exists within the scientific community for new, rare isotopes. One is that the properties of particular isotopes often hold the key to understanding some aspect of nuclear science. Another is that the rate of certain nuclear reactions involving rare isotopes can be important for modeling astronomical objects, such as supernovae. Yet another is that the properties of atomic nuclei can be used to test nature’s fundamental symmetries by searches for deviations from known symmetry laws. Finally, the production of isotopes benefits many branches of science and medicine as th isotopes can be used as sensitive probes of biological or physical processes. separator. Our current research is focused on preparing for experiments at FRIB where we hope to discover nearly 1,000 new isotopes. Simultaneously, we will study the nuclear reactions that produce new isotopes and work to better understand the best ways to produce any given isotope. We use and work to improve the modeling code LISE++, which involves interesting problems in computational science. Research in this area includes study and design of magnetic ion optical devices. learning the various nuclear production mechanisms and improving models to describe them. This background allows one to contribute to science by making new isotopes, but also prepares one for a broad range of careers in academia, government (e.g. national security), and industry. The tools for production and separation of rare isotopes gives scientists access to designer nuclei with characteristics that can be adjusted to the research need. For example, super-heavy isotopes of light elements, such as lithium, have a size nearly five times the size of a normal lithium nucleus. The existence of such nuclei allows researchers to study the interaction of neutrons in nearly pure neutron matter, similar to what exists in neutron stars. For production of new isotopes, the approach that I have helped develop is called in-flight separation; where a heavy ion, such as a uranium nucleus, is broken up at high energy. This produces a cocktail beam of fragments that are filtered by a downstream system of magnets called a fragment KEYWORDS Rare Isotope Production | Ion Optics | Drip Line Search The rich variety of nuclei is indicated by the depiction of three isotopes 4 He, 11 Li, and 220 Ra overlaid on the chart of nuclides where black squares indicate the combination of neutrons and protons that result in stable isotopes, yellow those produced so far, and green those that might exist. Nuclei like 11 Li have very different characteristics, such as a diffuse surface of neutron matter, than do normal nuclei. 57
