Abstract
We propose a non-destructive method to measure the trajectory of a single antiproton in a drift tube using position sensors based on the single electron transistor. We show that this recently developed device has sufficient sensitivity to detect the electric field of a moving charged particle. Comparing the trajectories of antiprotons and H− ions could allow a reliable determination of the gravitational mass of the antiproton.
