Abstract
The gravitational force acting on antiparticles has never been directl y measured to date. A method for measuring the gravitational effects o n antihydrogen by equilibrating the gravitational force with a magneti c gradient is discussed. The systematic and statistical errors inheren t to the measurement will be presented. It will be shown that a measur ement of gravity at 1% can be realised using similar to 5 x 10(5) anti hydrogen atoms. The production of antihydrogen atoms in conditions sui table for the measurement is also discussed.
