For the latest experiment, E05-115 in Hall C, we developed a new spectrometer system consisting of the HKS and HES; resulting in the best energy resolution ($E_{\\Lambda} \\simeq0.5$-MeV FWHM) and $B_{\\Lambda}$ accuracy ($B_{\\Lambda}\\leq0.2$ MeV) in $\\Lambda$-hypernuclear reaction spectroscopy.
