Time Projection Chambers (TPC) are very versatile detectors which are now widely used in different fields of nuclear physics. SpiRIT and AT-TPC are two TPCs that have been developed at MSU recently. 
SpiRIT has been constructed to fit the SAMURAI magnet in the RIBF facility of RIKEN, Japan to constrain the nuclear equation of state. Different solid targets of Pb isotopes are varied in combination with Pb beams to obtain the largest and smallest neutron asymmetry to probe the symmetry energy term at 270 AMeV. Several ancillary detectors are placed around the TPC to trigger on the heavy ion collisions. Negative and positive pions created during those collisions are counted and their ratio will be compared to theoretical models of the equation of state.
AT-TPC is an active target TPC developed for the new low energy ReA3 line of the  NSCL. This detector is widely used for transfer reactions but also for fission experiments with the conjunction of a solid target in the chamber. After presenting the analysis framework, the first experiments performed will be shown as well as future projects in the coming years.
