Silicon tracker array for RIB experiments at SAMURAI

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