Highly efficient charged particle veto detector CUP

• A novel, highly efficient, plastic scintillator detector has been constructed. The primary application of the detector is to act as a veto device in heavy-ion-induced fusion-evaporation reactions, in which the structure of proton-rich nuclides is investigated by gamma-ray spectroscopy methods. The detector rejects events in which light charged particles, like protons and alpha particles, are emitted in the evaporation process, facilitating selection of reaction channels associated with emission of only neutrons. The detector was used in a EUROBALL experiment, with achieved efficiencies of 80% and 63% for protons and alpha particles, respectively. The design of the detector, its performance and limitations are discussed.
