Progress on Data Collection and Analysis with the NIFFTE TPC

The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) collaboration has constructed and tested a Time Projection Chamber (TPC) designed to measure fission cross sections to a higher accuracy than has been achieved previously. In this talk I will describe the status of the fission TPC and progress on measuring the alpha decay to spontaneous fission branching ratio of Cf-252.
