The SAMURAI Pion Reconstruction and Ion-Tracker Time Projection Chamber (S$\pi$RIT TPC) was designed to enable measurements of heavy ion collisions with the SAMURAI spectrometer at the RIKEN Radioactive Isotope Beam Factory and provide constraints on the Equation of State of neutron-rich nuclear matter. The S$\pi$RIT TPC has a 50.5 cm drift length and an 86.4 cm $\times$ 134.4 cm pad plane with 12,096 pads that are equipped with the Generic Electronics for TPCs readout electronics. The S$\pi$RIT TPC allows excellent reconstruction of particles and provides isotopic resolution for pions and other light charged particles across a wide range of energy losses and momenta. Details of the S$\pi$RIT TPC are presented, along with discussion of the TPC performance based on cosmic ray and experimental data.

  1. Relaxation Kernel, Spectral Dissipation, and Global Convergence of Blahut--Arimoto Dynamics

    cs.IT 2026-04 unverdicted novelty 7.0

    The Blahut-Arimoto dynamics converges globally to nondegenerate stationary states because its free-energy decrease is controlled by a relaxation kernel that equals the Fisher-Rao Hessian and produces local spectral co...

    cs.IT 2026-04 unverdicted novelty 7.0

    Establishes chi^2-dissipation identities, spectral decomposition of Lyapunov functions, and explicit KL convergence factors for Blahut-Arimoto dynamics.

  3. Large amplification of the isospin-dependence of proton emitting source size in radioactive heavy-ion collisions: a signal of n-p correlation

    nucl-ex 2026-04 unverdicted novelty 6.0

    Proton emitting source size is amplified by 24% in neutron-rich versus neutron-deficient tin collisions, revealing a beyond-mean-field short-range n-p correlation effect.
