Beam physics studies into the design and optimization of a novel low energy antimatter research facility

Antiprotons, stored and cooled at low energies in a storage ring or at rest in traps, are highly desirable for the investigation of a large number of basic questions on fundamental interactions, on the static structure of exotic antiprotonic atomic systems or of (radioactive) nuclei as well as on the time-dependent quantum dynamics of correlated systems. Fundamental studies include for example CPT tests by high-resolution spectroscopy of the 1s-2s transition or of the ground-state hyperfine structure of antihydrogen, as well as gravity experiments with antimatter. In addition, low-energy antiprotons are the ideal and perhaps the only tool to study in detail correlated quantum dynamics of few-electron systems in the femto and sub-femtosecond time regime.

Antimatter experiments are at the cutting edge of science; impressively underlined through the award of ‘most important physics breakthrough’ in 2010 to the successful trapping of antihydrogen by physicsworld. They are, however, very difficult to realize and presently limited by the performance of the only existing facility in the world, the Antiproton Decelerator (AD) at CERN. To enable the efficient investigation of essentially all these important questions, a new experimental facility, the Extra Low ENergy Antiproton ring (ELENA) will be built.

The BeaPhy project focuses on research into the beam physics of ELENA and will address some of the key challenges in the design, construction and operation of the new research infrastructure ELENA.
