Abstract: In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is usually considered a source of background which can be removed effciently using the so-called fission-tagging or fission-veto technique. For this purpose a new compact and fast fission chamber has been developed. The design criteria and technical description of the chamber are given within the context of a measurement of the 233U(n, γ) cross-section at the n TOF facility at CERN, where it was coupled with the n TOF Total Absorption Calorimeter. For this measurement the fission detector was optimized for time resolution, actinide mass, minimization of material in the neutron beam and for alpha-fission discrimination. The performance of the fission chamber and its application as a fission tagging detector are discussed.
