All three experiments obtained a spectrum for Λ12B, which is the most characteristic p-shell hypernucleus and is commonly used for calibration. Additionally, a new kaon spectrometer, HKS (E01-011), a new electron spectrometer, HES, and a new splitting magnet (E05-115) were added to produce new data sets of precision, high-resolution hypernuclear spectroscopy. These later experiments used a modified experimental design, the "tilt method," to dramatically suppress the large electromagnetic background, and allowed for a substantial increase in luminosity. Since the pioneering experiment E89-009 studying hypernuclear spectroscopy using the (e,e'K+) reaction was completed, two additional experiments, E01-011 and E05-115, were performed at Jefferson Lab. Experiments with the High Resolution Kaon Spectrometer at JLab Hall C and the new spectroscopy of Λ12B hypernuclei
