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

TL;DR

The Notre-Dame Cube is an active-target time-projection chamber designed for radioactive beam experiments, enabling detailed reaction studies and detector development with low-intensity radioactive beams.

Contribution

We developed and characterized the ND-Cube, an innovative active-target detector, and demonstrated its application in measuring fusion cross sections and scattering events with radioactive beams.

Findings

Successfully commissioned with a $^{7}$Li beam

Measured $^{40}$Ar + $^{7}$Li fusion cross sections

Investigated $^{7}$Li($ ext{alpha}$,$ ext{alpha}$)$^{7}$Li scattering

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 $\mathit{TwinSol}$ 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($\alpha$,$\alpha$)$^{7}$Li scattering events. The ND-Cube will be used to study a range of reactions using light radioactive ions produced at low energy.
