On June 22, 2022, the first experiment at FRIB, which studied the beta decay of calcium-48 fragments that are so unstable that they only exist for mere fractions of a second, concluded successfully. FRIB's first scientific user experiment had participation from Argonne National Laboratory, Brookhaven National Laboratory, Florida State University, FRIB, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, Louisiana State University, Los Alamos National Laboratory, Mississippi State University, Oak Ridge National Laboratory, and the University of Tennessee. On November 14, 2022, the results of the first experiment were published in Physical Review Letters.
