Decay spectroscopy at the NSCL

The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University has a long list of successful experimental programs in fast-beam decay spectroscopy. The programs included studies of the evolution of nuclear structure away from the valley of stability, decay studies that drive astrophysical phenomena, the use of decays to probe fundamental interactions, and many more. To achieve such a diverse program, the NSCL hosted a plethora of experimental equipment, including implantation detectors, γ-ray arrays for high resolution spectroscopy, total absorption spectrometers, proton detectors, time projection chambers, and more. In this talk I will attempt to give an overview of the experimental decay program at the NSCL and provide some specific examples and their scientific impact. Looking towards the future, the decay spectroscopy program at FRIB is built on the success of the NSCL experimental program. It is therefore crucial to learn from the experiences of the decay spectroscopy users, and move forward as a community to tackle new scientific challenges at FRIB.
