The Mario Schenberg (Gravitational Wave Detector, Antenna, or Brazilian Graviton Project[1]) is a spherical, resonant-mass, gravitational wave detector run by the Physics Institute of the University of Sao Paulo, named after Mário Schenberg. Similar to the Dutch-run MiniGRAIL, the 1.15 ton, 65 cm diameter spherical test mass is suspended in a cryogenic vacuum enclosure, kept at 20 mK; and the sensors (transducers) for this detector/antenna are developed at the National Institute for Space Research (INPE), in Sao Jose' dos Campos, Brazil.[2][3]
