Query: Experimental techniques and performance of $\Lambda$-hypernuclear
  spectroscopy with the $(e,e^{\prime}K^{+})$ reaction   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.
