Measurement of the Neutron Induced Fission Cross Section on Transuranic (TRU) Elements at the n_TOF Facility at CERN.

During the 2004 campaign, the n_TOF collaboration measured neutron fission cross sections for ²³³U, ^241,243Am, ²⁴⁵Cm, as well as the fission standards ^235,238U, using a sealed Fission Ionization Chamber (FIC). The setup included a total of 16 targets and 18 electrodes mounted together in a 50-cm length chamber, allowing the measurements of all isotopes at the same time, thus in the same experimental conditions. A brief description of the facility and of the detector setup will be presented followed by the preliminary results of the analysis of ²³⁵U, ²³³U, and ²⁴⁵Cm from thermal energies up to some tenths of MeV.
