The Enge Split-Pole Spectrograph (SPS), formerly at Yale University, has recently been installed at Florida State University with a complement of new and upgraded auxiliary detectors and data acquisition systems. This setup can be used to measure nuclear structure information such as excitation energies, branching ratios and angular distributions of states populated via transfer reactions. The auxiliary detector systems, in conjunction with the SPS, will be used for a variety of nuclear structure and astrophysics applications, including (but not limited to) indirect measurements of reaction rates involving proton-rich nuclei, spectroscopic factors for exploring complete proton shell closures, unbound single proton states in the fp-shell, super-radiance in the sd-shell, and the measurement of (alpha, p) reactions important in X-ray burst nucleosynthesis. The commissioning and first scientific runs with the SPS will be discussed in addition to developments with auxiliary instrumentation.
