The objective of this project was the development of a borehole logging system based on neutron activation analysis or neutron capture gamma ray spectroscopy. The 2-inch-diameter borehole probe contains an intrinsic germanium detector, a canister-type solid cryogen cooling system, and associated electronics. A brief statement of the design goals, a technical description of important engineering features, and the test results obtained are included.
