%X Four detector modules, built from three different LYSO crystals and two different types of light sensors  (PMTs and SiPM arrays), have been tested with a deuteron beam from  100  MeV  –  270  MeV at the COSY accelerator facility for the srEDM project at the Forschungszentrum Jülich in Germany.  The detector modules were arranged in a cluster and mounted on a positioning table. The deuteron beam was targeted at the center of each individual crystal  for data analysis.   The signals were digitized using a 14  bit,  250  MS/s  flash  ADC. Further, the energy spectra were calibrated using the known beam energies from the accelerator. From  the calibrated spectra,  the  energy resolution was calculated.   A resolution of 3%  for the low energies and down to 1% for the high energy of 270 MeV was achieved.  A deuteron reconstruction efficiency of almost 100% for low energies and around 70% for high energies was achieved.  The SiPM light sensor showed a very good performance and will be used for the next generation of detector modules.
