The Active Target Time Projection Chamber (AT-TPC)

The Active Target Time Projection Chamber (AT-TPC) at the NSCL-MSU is a novel active target detector tailored for low-energy nuclear reactions in inverse kinematics with exotic nuclei. The AT-TPC allows for a total 3D reconstruction of the reaction and provides high luminosity. The broad physics program of the AT-TPC covers many different fundamental questions in low-energy nuclear physics. The AT-TPC is currently installed in the ReA3 reaccelerated beam line at the NSCL. This beam line provides exotic beams at low energies very well adapted for the physics program of the AT-TPC. The AT-TPC can be operated under a magnetic field that enhances the identification of the particles while improving the resolution through the measurement of the magnetic rigidity. For fast beams, the current AT-TPC will feature a pad plane with an exit hole that will allow us to couple the detector to other apparatus, like the S800 spectrograph at the NSCL. Such detection scheme will greatly benefit from systems like SOLARIS featuring a solenoid magnet for studies with fast beams. Recent results and the future experimental program of the ATTPC will be discussed in this talk.
