A measurement of the gravitational acceleration of the antiproton
Description
An experiment is being developed which will compare the acceleration, g, of the antiproton in the earth's gravitational field with that of Hminus ions. This measurement will constitute the first direct test of the Weak Equivalence Principle (WEP) for antimatter. Low energy antiprotons from the LEAR facility at CERN will be decelerated, cooled and launched into a field free region, and the time of flight to a detector will determine g. The technical aspects of the experiment and our progress in the different areas are presented. 4 refs., 1 fig
