Beam lines are also available for experiments where Users bring their own equipment. Users of ATLAS take advantage of the existing experimental equipment such as, for example, the Canadian Penning Trap (CPT), the Fragment Mass Analyzer (FMA), the magnetic spectrograph and Gammasphere. These beams are used mostly to study nuclear reactions of astrophysical interest and for nuclear structure investigations.
About 20% of the beam-time is used to generate secondary radioactive beams.

The full range of all stable ions can be produced in ECR ion sources, accelerated in the world?s first superconducting linear accelerator for ions to energies of 7-17 MeV per nucleon and delivered to one of several target stations. It provides a wide range of beams for nuclear reaction and structure research to a large community of users from the US and abroad. The ATLAS facility is a leading facility for nuclear structure research in the United States. The first extractant is selected from bis(2-ethylhexyl)hydrogen phosphate (HDEHP) and mono(2-ethylhexyl)2-ethylhexyl phosphonate (HEH(EHP)) and the second extractant is selected from N,N,N,N-tetra-2-ethylhexyl diglycol amide (TEHDGA) and N,N,N,N-tetraoctyl-3-oxapentanediamide (TODGA).ĪTLAS is a national user facility at Argonne National Laboratory in Argonne, Illinois. The scrubber discharge is stripped with a simple buffering agent and a second chelating agent in the pH range of 2.5 to 6.1 to produce actinide and lanthanide streams and spent organic diluents. Scrubbing the organic stream with a dicarboxylic acid and a chelating agent to form a scrubber discharge. The process of the invention is the separation of minor actinides from lanthanides in a fluid mixture comprising, fission products, lanthanides, minor actinides, rare earth elements, nitric acid and water by addition of an organic chelating aid to the fluid extracting the fluid with a solvent comprising a first extractant, a second extractant and an organic diluent to form an organic extractant stream and an aqueous raffinate.
