In particular, KOBRA(the Korea Broad Acceptance Recoil Spectrometer & Apparatus) and LAMPS(the Large-Acceptance Multi-Purpose Spectrometer) will be constructed for the nuclear physics experiments.The primary goal of KOBRA is to study the structure of exotic nuclei near drip lines and various astrophysical processes at low energies. On the other hand, LAMPS will investigate the density dependence of the nuclear symmetry energy in wide beam energy range up to 2 times normal nuclear densities.
