Fig. 4: Time structure of the annihilation events from escaped antihydrogen.
From: Observation of the effect of gravity on the motion of antimatter
The number of detected events (left ordinate) is plotted as a function of time as the magnets are ramped down. This figure represents the sum of the seven trials having bias 0g. The dashed line (right ordinate) illustrates the calculated axial well depth during the magnet ramp-down. The excluded events fail the time cut.
