The Lund-York-Cologne-Calorimeter (LYCCA) is a detector array consisting of 24 Double-sided Silicon Strip Detectors (DSSSDs) and a digital data acquisition system using the ASIC based AIDA front-end electronics. Its more than 1.5π angular coverage, customizable detector positioning and 32 strips per detector side allow for precise measurement of angular correlations of particles with high efficiency. The setup was used during the NUSTAR-PRESPEC campaign and will be part of the NUSTAR HISPEC/DESPEC experiments at FAIR@GSI. During the past two years substantial improvements to LYCCA have been implemented, which will be detailed in the talk. After the upgrades a series of nuclear astrophysics experiments with a nat.C(α, α′)C* reaction with beam energies between 20 and 28.5 MeV were conducted at the 10 MV FN-tandem accelerator of the Institute for Nuclear Physics of the University of Cologne. Preliminary results from the latest two beam times will be presented. Supported by GSI F&E KREITE 1416.
