摘要：

The Mario Schenberg gravitational wave detector has been constructed at its site in the Physics Institute of the University of Sao Paulo as programmed by the Brazilian Graviton Project, under the full support of FAPESP (the Sao Paulo State Foundation for Research Support). We are preparing it for a first commissioning run of the spherical antenna at 4.2 K with three parametric transducers and an initial target sensitivity of h similar to 2 x 10(-21) Hz(-1/2) in a 60 Hz bandwidth around 3.2 kHz. Here we present the status of this project.
