Abstract

Sensitivity studies have shown that the ¹⁵O(α, γ)¹⁹Ne reaction is the most important reaction rate uncertainty affecting the shape of light curves from Type I X-ray bursts. This reaction is dominated by the 4.03 MeV resonance in ¹⁹Ne. Previous measurements by our group have shown that this state is populated in the decay sequence of ²⁰Mg. A single ²⁰Mg(βpα)¹⁵O event through the key ¹⁵O(α, γ)¹⁹Ne resonance yields a characteristic signature: the emission of a proton and alpha particle. To achieve the granularity necessary for the identification of this signature, we have upgraded the Proton Detector of the Gaseous Detector with Germanium Tagging (GADGET) into a time projection chamber to form the GADGET II detection system. GADGET II has been fully constructed, and is entering the testing phase.
