Abstract
The first experiment E89-009/HNSS has made the key demonstration and feasibility test on the electroproduction of hypernuclei. Based on the experiences learned, the newly approved experiment, E01-011, is under preparation with a new method in tagging the scattered electrons and a newly designed and built kaon spectrometer, that optimize the usage of electron beam for high precision hypernuclear spectroscopy. Comparing to HNSS, the hypernuclear yield and signal over background ratio will be increased by about 56 and 10 times, respectively. Most importantly, we expect to obtain an energy resolution of about 300 keV. This experimental setup will open a door for high yield, high quality, and high precision hypernuclear spectroscopic study in a wide mass range. The immediate goal of E01-011 is to study hypernuclei in the medium heavy region.
