  • Abstract
    We describe an experiment to measure the Newtonian gravitational constant G. The gravitational forces of large field masses on test masses are measured using a beam balance. A preliminary result with a relative uncertainty of 220/spl times/10/sup -6/ has been published recently. In the meantime various modifications of the experiment have been made.
