Antihydrogen physics: gravitation and spectroscopy in AEgISThis paper was presented at the International Conference on Precision Physics of Simple Atomic Systems, held at École de Physique, les Houches, France, 30 May – 4 June, 2010.

R. Ferragut, А. С. Белов, G. Bonomi, I. Boscolo et autres

AEgIS (Antimatter experiment: gravity, interferometry, spectroscopy) is an experiment approved by CERN with the goal of studying antihydrogen physics. In AEgIS, antihydrogen will be produced by charge exchange reactions of cold antiprotons with positronium atoms excited in a Rydberg state (n > …

Measuring the fall of antihydrogen: the AEgIS experiment at CERN

M. Doser, Y. Allkofer, C. Amsler, А. С. Белов et autres

Considerable efforts have been made and are still being made to verify the validity of the principle of the equivalence of gravitational and inertial mass, one of the cornerstones of the classical theory of general relativity. Specific attempts at quantummechanical formulations of …

High-Resolution Laser Spectroscopy on the Negative Osmium Ion

Ulrich Warring, Michele Amoretti, C. Canali, Andreas Fischer et autres

We have applied a combination of laser excitation and electric-field detachment to negative atomic ions for the first time, resulting in an enhancement of the excited-state detection efficiency for spectroscopy by at least 2 orders of magnitude. Applying the new method, a …

Creation, diagnostics and manipulation of a non-neutral one-component plasma

R. Heyne

The sympathetic cooling of ions with electrons is a well-established technique that\nis routinely used on negative particles ranging from antiprotons to molecules. An electron\nbeam can be captured and confined in a Penning trap, forming a non-neutral onecomponent\nplasma. Due to the high frequency …

Formation Of A Cold Antihydrogen Beam in AEGIS For Gravity Measurements

G. Testera, А. С. Белов, G. Bonomi, I. Boscolo et autres

The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the antihydrogen initial conditions are shown. The resulting velocity distribution …
