An innovative solution for the forward end-cap CALIFA calorimeter of R{sup 3}B is under investigation consisting of two scintillation crystals, LaBr{sub 3} and LaCl{sub 3}, stacked together in a phoswich configuration with one readout only. This dispositive should be capable of a good determination of the energy of protons and gamma radiation. This composite detector allows to deduce the initial energy of charged particles by DELTAE1+DELTAE2 identification. For gammas, the simulations show that there is a high probability that the first interaction occurs inside the scintillator at few centimeters, with a second layer, the rest of the energy is absorbed, or it can be used as veto event in case of no deposition in the first layer. One such a detector has been tested at the Centro de MicroAnalisis de Materiales (CMAM) in Madrid. Good resolution and time signal separation have been achieved.
