According to some theories of gravity, antimatter will fall faster than matter in the earth's gravitational field. An experiment to measure the gravitational force on the antiproton is under construction. Antiprotons of a few MeV from the LEAR facility of CERN will be slowed down and caught in a large Penning electromagnetic trap. They will then be cooled and transferred to Penning cooling and launching traps. The gravitational acceleration will be measured by the time-of-flight in a drift tube shielding stray electronic fields, and will be compared with that measured for H/sup /minus// ions. Progress on a number of fronts is described. 9 refs., 2 figs.
