摘要

We report on the performance of a 1 m$^{3}$ TPC filled with CF$_{4}$ at 3bar, immersed in liquid scintillator and viewed by photomultipliers. Particledetection, event identification and localization achieved by measuring both thecurrent signal and the scintillation light are presented. Particular featuresof $\alpha$ particle detection are also discussed. Finally, the ${54}$Mnphotopeak, reconstructed from the Compton scattering and recoil angle is shown.
