The characteristics and performance of an annular parallel plate avalanche counter (APPAC) developed for performing heavy ion nuclear physics experiments are presented. The main motive of developing this detector system is to perform Coulomb excitation (Coulex) experiments using particle–γ coincidence technique. The Coulex measurements are performed with APPAC and clover germanium detectors. The APPAC has a two electrode geometry and provides...
