Description

The Low Background Facility (LBF) at Lawrence Berkeley National Laboratory in Berkeley, California operates in two unique facilities—locally within a carefully-constructed, low background cave; and remotely at an underground location (~500 m.w.e) nearby in Oroville, CA. These facilities provide a variety of gamma spectroscopy services to low background experiments primarily in the form of passive material screening for primordial radioisotopes (U, Th, K) or common cosmogenic/anthropogenic products, as well as active screening via Neutron Activation Analysis for specific applications. A general overview of the facilities, services, and sensitivities will be discussed. Recent activities and upgrades will also be presented, including the recent installation of a 3π muon veto at the surface station, addition of old Pb to counting shields, and environmental monitoring of Fukushima fallout.
