TL;DR
The GBAR experiment at CERN is developing methods to measure how antihydrogen atoms fall under gravity, with initial tests conducted and future plans outlined to explore antimatter gravity effects.
Contribution
This paper reports the current status and experimental setup of the GBAR project, including integration with CERN's ELENA ring and initial testing results.
Findings
Initial tests with antiproton and positron beams completed
Connected to CERN's ELENA low energy antiproton ring
Outlining future experimental plans
Abstract
The GBAR experiment aims at measuring the free fall of antihydrogen atoms in the terrestrial gravitational field. It is located at CERN in the AD area. It is the first experiment which has been connected to the ELENA low energy antiproton ring that started commissioning in the summer of 2018. First tests with antiproton and positron beams were performed in summer and fall of 2018. The status and plans of the experiment are described in this document.
