The missing-mass spectroscopy of $$\Lambda$$ hypernuclei via the $$(e,e^{\prime}K^{+})$$ reaction has been developed through experiments at JLab Halls A and C in the last two decades. 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. This paper describes the characteristics of the $$(e,e^{\prime}K^{+})$$ reaction compared to other reactions and experimental methods. In addition, the experimental apparatus, some of the important analyses such as the semi-automated calibration of absolute energy scale, and the performance achieved in E05-115 are presented.
