Eur. Phys. J. A (2022) 58:223 This work describes a silicon tracker system developed for experiments with
proton-rich radioactive ion beams at the SAMURAI superconducting spectrometer
of RIBF at RIKEN. The system is designed for accurate angular reconstruction
and atomic number identification of relativistic heavy ions and protons which
are simultaneously produced in reactions motivated by studies of proton capture
reactions of interest for nuclear astrophysics. The technical characteristics
of the tracking array are described in detail as are its performance in two
pilot experiments. The physics justification for such a system is also
presented.
