During the 2004 campaign, the n_TOF collaboration measured neutron fission cross sections for ^{233}U, ^{241,243}Am, ^{245}Cm, as well as the fission standards ^{235,238}U, 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 ^{235}U, ^{233}U, and ^{245}Cm from thermal energies up to some tenths of MeV.
