Beschreibung:
<jats:p>The upgrade of the scintillating bars detector, used in the experiments of the ASACUSA Collaboration at the CERN Antiproton Decelerator is presented. The detector consists of several modules, each one made of ≈1m long scintillating bars, which allow the detection of the charged particles produced in the annihilations of antiprotons and antihydrogens. The mechanics, the electronic readout and the data acquisition system upgrade are described.</jats:p>
