The E01-011 (HKS) experiment is the second-generation hypernuclear
spectroscopy experiment by the (e,e'K+) reaction at the Thomas
Jefferson National Accelerator Facility (JLab). This is the
continuation of the hypernuclear physics program at JLab Hall C
established by the E89-009 (HNSS) experiment which demonstrated
feasibility of electroproduction of hypernuclei with sub-MeV
resolution. The immediate goal of the HKS experiment is to study
hypernuclei in the medium-heavy region. To achieve this goal, the new
high-resolution kaon spectrometer (HKS) was constructed and built,
and new method in tagging the scattered electrons, the so called
Tilt method, was implemented. Preliminary high-resolution spectra
of 7Λ He, 12Λ B
and 28Λ Al
hypernuclei are presented and discussed.
