Observations were performed by using Prof. Joe Weber's torsion balance, a room-temperature instrument that was constructed by University of Maryland under a subcontract from Raytheon, and was installed at LANL in Summer 1988. The torsion balance was mounted at a fixed location, close to the edge of a rotating table (1 RPM rotational speed) that Raytheon had constructed and moved to Los Alamos, NM. As the table rotated, the tritium-filled container (neutrino source) and the deuterium-filled container (that provided a newtonian force reference) were sensed by the instrument. At the time of writing of this Report, the results of the measurements are not fully conclusive. A six-month Contract extension, expected to last until 31 December 1989, will provide the final answer whether or not we could observe repulsion forces, attributable to neutrino pressure, with the torsion balance.
