Description
Active Targets are a choice in low-energy nuclear physics when luminosity and high detection efficiency are needed. When combined with a solenoid magnet, their energy dynamic range and particle identification capabilities are greatly enhanced. The Active Target Time Projection Chamber (AT-TPC) of the FRIB is one such detector, a powerful tool to investigate direct and resonant reactions where the excitation function has to be measured continuously with high precision. As an example, 22Mg(α,p) at low bombarding energies was measured. This is first direct measurement of this reaction that plays a key role for Type-I X-ray burst (XRB) light curves. In this talk I will introduce the Active Target technique and I will present the results obtained in this experiment and future possibilities.
