In the pursuit of identifying rare two-particle events within GADGET II Time Projection Chamber (TPC), this paper presents a comprehensive approach for leveraging Convolutional Neural Networks (CNNs) and various data processing methods. To address inherent complexities 3D TPC track reconstructions, is expressed in 2D projections 1D quantities. This capitalizes on diverse modalities TPC, allowing efficient representation distinct features events, with no loss topology uniqueness....
Background: The established GAseous Detector with GErmanium Tagging (GADGET) detection system is used to measure weak, low-energy β-delayed proton decays.It consists of the gaseous Proton equipped a MICROMEGAS (MM) readout detect protons and other charged particles calorimetrically, surrounded by Segmented Germanium Array (SeGA) for high-resolution prompt γ-rays.Purpose: To upgrade GADGET's operate as compact Time Projection Chamber (TPC) detection, 3D imaging identification singleand...
Sensitivity studies have shown that the 15 O(α, γ) 19 Ne reaction is most important rate uncertainty affecting shape of light curves from Type I X-ray bursts. This dominated by 4.03 MeV resonance in Ne. Previous measurements our group this state populated decay sequence 20 Mg. A single Mg(βp α) O event through key yields a characteristic signature: emission proton and alpha particle. To achieve granularity necessary for identification signature, we upgraded Proton Detector Gaseous with...
15 O( α , γ ) 19 Ne is regarded as one of the most important thermonuclear reactions in type I X-ray bursts. For studying properties key resonance this reaction using β decay, existing Proton Detector component Gaseous with Germanium Tagging (GADGET) assembly being upgraded to operate a time projection chamber (TPC) at FRIB. This upgrade includes associated hardware well software and paper mainly focusses on upgrade. The full detector set up simulated ATTPCROOTv 2 data analysis framework for...
The Particle X-ray Coincidence Technique (PXCT) was originally developed to measure average lifetimes in the $10^{-17}-10^{-15}$~s range for proton-unbound states populated by electron capture (EC). We have designed and built Lifetimes Branching Ratios Apparatus (LIBRA) be used stopped-beam area at Facility Rare Isotope Beams that extends PXCT both decay branching ratios of resonances EC/$\beta^+$ decay. first application LIBRA aims obtain essential nuclear data from $^{60}$Ga constrain...
