The information on the baryon-baryon interaction with strange-quarks is essential to understand the nature of extreme astrophysical objects such as neutron starts, and it can be obtained only via studying hypernuclei, nuclei with hyperons which are baryons with strange quarks. Hypernuclei have been extensively studied by experiments with meson and electron beams, however, these experiments can reach only hypernuclei near the ß-stability line because these experiments produced hypernuclei as converted from stable target nuclei. The HypHI project will be able to study a variety of hypernuclei very far from the ß-stability line by means of hypernuclear spectroscopy with heavy ion beams and rare-isotope beams, and it can study in detail hyperon-nucleon interaction in the neutron rich nuclear medium and hypernuclear magnetic moments. The information on very neutron rich hypernuclei may give very unique information on the baryon-baryon interactions in the core of neutron stars. This proposal intends to develop state-of-art Time-Of-Flight detectors for the HypHI experiment at the GSl current facility for the hypernuclear identification.
