Abstract:
The main goal of the AEgIS experiment at CERN is to test the weak equivalence
principle for antimatter. AEgIS will measure the free-fall of an antihydrogen beam traversing
a moir´e deflectometer. The goal is to determine the gravitational acceleration ¯ g with an initial
relative accuracy of 1% by using an emulsion detector combined with a silicon m-strip detector to
measure the time of flight. Nuclear emulsions can measure the annihilation vertex of antihydrogen
atoms with a precision of 1–2 mm r.m.s. We present here results for emulsion detectors operated
in vacuum using low energy antiprotons from the CERN antiproton decelerator. We compare with
Monte Carlo simulations, and discuss the impact on the AEgIS project.
