Texas Active Target (TexAT) - design, commissioning and first results.

Texas Active Target is a general purpose time projection chamber (TPC) embedded into shells of Si and CsI(Tl) detector arrays. It is designed for nuclear reactions studies with rare isotope beams. The main focus of physics program with TexAT is structure of exotic nuclei and nuclear astrophysics. TexAT employs Micro-MEsh GAseous Structure ("Micromegas") detector and Generic Electronic System for TPCs (GET). We will discuss design, performance, and results of the first commissioning experiments performed with radioactive beams produced by Momentum Achromat Recoil Separator (MARS) at the Texas A&M University Cyclotron Institute.
