Abstract
The detection system of The Laboratory for Experimental Nuclear Astrophysics is described, including methods for measuring weak capture-γ-ray resonances. Improved γ γ-coincidence techniques are detailed, as well as the reduction of cosmic muon-induced background in the energy region of Eγ = 0.6 - 9.0 MeV by the use of compact cosmic muon anti-coincidence shields. These techniques reduced background count rates in the regions of Eγ = 0.6-3.0 and 3.0-9.0 MeV with respect to unshielded singles count rates by factors of 3600 and 21, respectively.
