Speaker
Description
LAG (Liquid Actuated Gravity) is an R&D experiment, funded by the Italian National Institute of Nuclear Physics (INFN), for the development and testing of a new actuation technique for gravity experiments, based on a liquid field mass. The basic idea of the experiment is to modulate the gravitational force acting on a test mass by controlling the level of a liquid in a suitable container, thereby producing a periodically varying gravitational force without moving parts (apart from the liquid level) close to the test mass. The first scientific goal is to improve upon present limits on the gravitational inverse-square law in the mm to cm distance region. A prototype has been assembled for testing with a torsion pendulum facility in Napoli, and we are now taking data. We will describe the apparatus, report on present results and describe the next steps, and the scientific perspectives for the LAG experiment.
