Antimatter

Oral

Throughout its existence, the Standard Model has proven very successful in describing fundamental interactions of elementary particles. However, one observation, which has yet to be understood, is the asymmetry between the abundance of matter and antimatter in the universe. The BASE experiment, located at CERN’s Antiproton Decelerator (AD) facility, measures the fundamental properties of...

Antimatter

Oral

C$_2^-$ and other anionic molecules are produced with an electric discharge valve and accelerated to 1.8 keV in a pulsed electric field. The C$_2^-$ are then mass selected in a Wien filter. Subsequently the C$_2^-$ are decelerated in the static electric field of a resistive tube with a potential difference of 1.798 kV to reduce the energy of the particles to a trappable range. A digital RF...

Antimatter

Oral

The aim of the GBAR experiment is to measure the effect of gravity on antihydrogen atoms [1]. Those are created by interactions of antiprotons with a dense positronium cloud. The antiprotons are obtained from the decelerator complex at CERN now composed of two steps: the Antiproton Decelerator, in which the beam reaches 5 MeV energy, and ELENA where it is further decelerated to 100 keV....
