Measured and simulated performance of a four-segmented clover detector

Gamma rays with energies between 80 keV and 1500 keV produced by Ba-133 and Eu-152 standard sources are measured with the clover detector. Relative efficiencies and add-back factors are determined in both crystals and full clover modes. The add-back characteristics have been calculated using Monte-Carlo simulation code Geant4. The simulation and measurements agree very well.
