ResumenCEPA4 is a new phoswich array for the detection of high-energy protons and gammarays from nuclear reactions and spectroscopy of beta-delayed particles and gamma-rays. This new detector consists of four individual closely-packed scintillator detectors, each of them made of 4 cm of LaBr3(Ce) and 6 cm of LaCl3(Ce) in phoswich configuration (optically coupled and with a common readout). In this contribution we report on the results of a beam test performed at the Bronowice Cyclotron Centre (CCB) in Krakow, showing the response of this versatile instrument to high energy protons (70 - 230 MeV). Furthermore, we show that we can reconstruct the original energy of fast protons (E > 200 MeV) which pass through the total length of the crystal while still retaining a good energy resolution.
