There are a wide variety of phenomena that are of interest in exotic nuclei such as clustering, evolution of structure, and the role of nuclei in nucleosynthesis. With the availability of new radioactive beams, such as from ReA3 in the near future, we will have access to a broader range of these rare nuclei. Developments in detector technology are needed to make full use of these radioactive beams, which come with challenges such as low beam rates. The Active-Target Time Projection Chamber (AT-TPC) is a new generation time projection chamber being developed for nuclear physics experiments with beams of exotic nuclei. Its main feature is its tracking chamber, which has the ability to track beam and reaction particles. This tracking feature allows the detector to have good energy and angular resolution as well as a large angular acceptance for reaction products. In this presentation, I will present an overview of the AT-TPC project and its current status including details of some the development projects that the group is currently involved in, which includes testing and simulation of components, target gases, and work with the half-scale Prototype AT-TPC. I will also mention some future plans envisioned for the Prototype detector.
