Prototype AT-TPC: a new active target time projection chamber for low-energy reactions
ORAL
Abstract
An active target time projection chamber (AT-TPC) is being developed at the National Superconducting Cyclotron Laboratory. The detector will be coupled to the forthcoming ReA3 accelerator complex, providing a powerful tool for reaction studies with low-energy radioactive beams. The Prototype AT-TPC, a half scale version of the future AT-TPC, has recently been completed. The first in-beam experiment was performed at the University of Notre Dame in April. The elastic and inelastic alpha scattering on radioactive $^{6}$He beams were measured at low energy to study the neutron transfer or resonant processes. The $^{6}$He beam at 14 MeV was produced by the Twinsol device, and directed to the Prototype AT-TPC operated with He:CO$_{2}$ gas mixtures. The design and the performances of the detector, and the results from the Notre Dame experiment will be presented.
