Description
This Fall the upgrade of the antiproton decelerator, the Extra Low ENergy Antiproton (ELENA) ring, will start operation at CERN opening a new era for antihydrogen research. In the context of the GBAR experiment aiming to study the gravitational behaviour of antimatter, our group from ETHZ proposed and is preparing a Lamb shift measurement of antihydrogen with an uncertainty of $100~\mathrm{ppm}$. This will allow to extract the antiproton charge radius at a level of $10\%$ and will provide a sensitive test of Lorentz and CPT symmetry. I will present the results of the setup commissioning with hydrogen atoms and plans for the upcoming beamtime with antiprotons.
