Describing the nuclear fission process requires high-precision data from experiments. We present results of an experimental campaign at the High-Intensity γ-Ray Source at TUNL, investigating the fission of actinides using linearly-polarized quasi-monochromatic photon beams between 6.2 and 13 MeV in the entrance channel. Mass, total kinetic energy and angular distributions of fission fragments have been measured simultaneously using a position-sensitive twin Frisch-grid ionization chamber.
