BaF2探测器的20厘米长（10辐射长度）和六边形横截面（直径5.2厘米）进行了测试，使用单色光子从标记光子设施在电子加速器MAMIA在美因茨。实验光谱的沉积能量为一个单一的探测器和一个阵列的七个模块比较非常好的Monte Carlo簇射模拟使用代码GEANT 3的预测。在高光子能量下，与单个模块的分辨率相比，观察到求和能谱的能量分辨率的显著改善（超过因子2）。
BaF2detectors of 20 cm length (10 radiation lengths) and hexagonal cross section (diameter 5.2 cm) were tested using monochromatic photons from the tagged-photon facility at the electron accelerator MAMIA at Mainz. The experimental spectra the deposited energy for a single detector and for an array of seven modules compare very well with the predictions of Monte Carlo shower simulations using the code GEANT3. At high photon energies a significant improvement (more than a factor 2) of the energy resolution is observed for the summed energy spectra as compared to the resolution of one single module.
