Design of the ECCE detector for the Electron Ion Collider

https://doi.org/10.1016/j.nima.2025.170240

Adkins, JK; Akiba, Y; Albataineh, A; Amaryan, M; Arsene, IC; Gayoso, C Ayerbe; Bae, J; Bai, X; Baker, MD; Bashkanov, M; et al (April 2025, Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment)

The EIC Comprehensive Chromodynamics Experiment (ECCE) detector has been designed to address the full scope of the proposed Electron Ion Collider (EIC) physics program as presented by the National Academy of Science and provide a deeper understanding of the quark–gluon structure of matter. To accomplish this, the ECCE detector offers nearly acceptance and energy coverage along with excellent tracking and particle identification. The ECCE detector was designed to be built within the budget envelope set out by the EIC project while simultaneously managing cost and schedule risks. This detector concept has been selected to be the basis for the EIC project detector.

Measuring the ¹⁵ O(α, γ) ¹⁹ Ne reaction in Type I X-ray bursts using the GADGET II TPC: Hardware

https://doi.org/10.1051/epjconf/202226011046

Wheeler, Tyler; Adams, A.; Allmond, J.; Alvarez Pol, H.; Argo, E.; Ayyad, Y.; Bardayan, D.; Bazin, D.; Budner, T.; Chen, A.; et al (January 2022, EPJ Web of Conferences)

Sensitivity studies have shown that the 15 O(α, γ) 19 Ne 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 19 Ne. Previous measurements by our group have shown that this state is populated in the decay sequence of 20 Mg. A single 20 Mg(βp α) 15 O event through the key 15 O(α, γ) 19 Ne 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.

Measuring the ¹⁵ O( α , γ ) ¹⁹ Ne Reaction in Type I X-ray Bursts using the GADGET II TPC: Software

https://doi.org/10.1051/epjconf/202226011034

Mahajan, Ruchi; Adams, A.; Allmond, J.; Alvarez Pol, H.; Argo, E.; Ayyad, Y.; Bardayan, D.; Bazin, D.; Budner, T.; Chen, A.; et al (January 2022, EPJ Web of Conferences)
Liu, W.; Wang, Y.; Guo, B.; Tang, X.; Zeng, S. (Ed.)
15 O( α , γ ) 19 Ne is regarded as one of the most important thermonuclear reactions in type I X-ray bursts. For studying the properties of the key resonance in this reaction using β decay, the existing Proton Detector component of the Gaseous Detector with Germanium Tagging (GADGET) assembly is being upgraded to operate as a time projection chamber (TPC) at FRIB. This upgrade includes the associated hardware as well as software and this paper mainly focusses on the software upgrade. The full detector set up is simulated using the ATTPCROOTv 2 data analysis framework for 20 Mg and 241 Am.
