Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research. By tonnage, separating natural uranium into enriched uranium and depleted uranium is the largest application. In the following text, mainly uranium enrichment is considered. This process is crucial in the manufacture of uranium fuel for nuclear power plants, and is also required for the creation of uranium-based nuclear weapons. Plutonium-based weapons use plutonium produced in a nuclear reactor, which must be operated in such a way as to produce plutonium already of suitable isotopic mix or grade.
Argonne National Laboratory is a federally funded research and development center in Lemont, Illinois, United States. Founded in 1946, the laboratory is owned by the United States Department of Energy and administered by UChicago Argonne LLC of the University of Chicago. The facility is the largest national laboratory in the Midwest.
Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a US National Laboratory located in Newport News, Virginia. Its stated mission is "to provide forefront scientific facilities, opportunities and leadership essential for discovering the fundamental structure of nuclear matter; to partner in industry to apply its advanced technology; and to serve the nation and its communities through education and public outreach."
Elastic recoil detection analysis (ERDA), also referred to as forward recoil scattering, is an ion beam analysis technique in materials science to obtain elemental concentration depth profiles in thin films. This technique is known by several different names. These names are listed below. In the technique of ERDA, an energetic ion beam is directed at a sample to be characterized and there is an elastic nuclear interaction between the ions of beam and the atoms of the target sample. Such interactions are commonly of Coulomb nature. Depending on the kinetics of the ions, cross section area, and the loss of energy of the ions in the matter, ERDA helps determine the quantification of the elemental analysis. It also provides information about the depth profile of the sample.
The Argonne Tandem Linac Accelerator System (ATLAS) is a U.S. Department of Energy scientific user facility at Argonne National Laboratory. ATLAS is the first superconducting linear accelerator for heavy ions at energies in the vicinity of the Coulomb barrier and is open to scientists from all over the world.
Muon spin spectroscopy, also known as µSR, is an experimental technique based on the implantation of spin-polarized muons in matter and on the detection of the influence of the atomic, molecular or crystalline surroundings on their spin motion. The motion of the muon spin is due to the magnetic field experienced by the particle and may provide information on its local environment in a very similar way to other magnetic resonance techniques, such as electron spin resonance and, more closely, nuclear magnetic resonance (NMR).
Neutron depth profiling (NDP) is a near-surface analysis technique that is commonly used to obtain profiles of concentration as a function of depth for certain technologically important light elements in nearly any substrate. The technique was first proposed by Ziegler et al. to determine the concentration profiles of boron impurities in silicon substrates, and later improved by Biersack and coworkers to much of its existing capabilities.
The Gammasphere is a third generation gamma ray spectrometer used to study rare and exotic nuclear physics. It consists of 108 Compton-suppressed large volume, high-purity germanium detectors arranged in a spherical shell.
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
The Canadian Penning Trap Mass Spectrometer (CPT) is one of the major pieces of experimental equipment that is installed on the ATLAS superconducting heavy-ion linac facility at the Physics Division of the Argonne National Laboratory. It was developed and operated by physicist Guy Savard and a collaboration of other scientists at Argonne, the University of Manitoba, McGill University, Texas A&M University and the State University of New York.
The program LISE++ is designed to predict the intensity and purity of radioactive ion beams (RIB) produced by In-flight separators. LISE++ also facilitates the tuning of experiments where its results can be quickly compared to on-line data. The program is constantly expanding and evolving from the feedback of its users around the world.
RAON is a South Korean particle physics laboratory within the Rare Isotope Science Project (RISP) that is being constructed in the outskirts of Daejeon neighboring Sejong, South Korea by the Institute for Basic Science (IBS). It was expected to be finished by 2021 before getting pushed back to 2025.
Marielle Chartier is a Professor of Particle Physics at the University of Liverpool in England. Her research investigates the phase diagram of nuclear matter using the ALICE experiment at the Large Hadron Collider (LHC) at CERN Her past work includes nuclear structure at the frontiers of the valley of stability.
The Laboratori Nazionali di Legnaro is one of the four major research centers of the Italian National Institute for Nuclear Physics (INFN). The primary focus of research at this laboratory is in the fields of nuclear physics and nuclear astrophysics, where five accelerators are currently used. It is one of the most important facilities in Italy for research in these fields. The main future project of the laboratory is the Selective Production of Exotic Species (SPES), in which various radionuclides will be produced for research and medicinal purposes.
