The Notre-Dame Cube: An active-target time-projection chamber for radioactive beam experiments and detector development

Abstract

Active-target detectors have the potential to address the difficulties associated with the low intensities of radioactive beams. We have developed an active-target detector, the Notre Dame Cube (ND-Cube), to perform experiments with radioactive beams produced at $TwinSol$ and to aid in the development of active-target techniques. Various aspects of the ND-Cube and its design were characterized. The ND-Cube was commissioned with a ${}^7$Li beam for measuring ${}^{40}$Ar + ${}^7$Li fusion reaction cross sections and investigating ${}^7$Li($\hat{I}\pm$,$\hat{I}\pm$)${}^7$Li scattering events. The ND-Cube will be used to study a range of reactions using light radioactive ions produced at low energy.
