Beam Stability and Life Time in Low Energy Storage Rings
ELENA at CERN’s AD and FLAIR will provide cooled beams of antiprotons at lower energies than currently achievable anywhere in the world. It will be crucial to have detailed knowledge about the achievable stability of the beam in the storage ring and the expected beam life times. Existing low energy storage rings, operating at keV beam energies, found strong limitations on beam intensity and reduced life time in experimental studies. The nature of these effects had not been fully understood for a very long time and only recently causes of these limits to beam current and life time were identified and reproduced in simulations.
This project will build up on initial studies and investigate all effects impacting on beam stability and establish realistic models of beam storage and cooling. New simulation tools shall be developed that enable start-to-end simulations of antiproton pulses through electrostatic low energy beam lines. These tools shall then be applied for an overall optimization of beam handling towards the various experiments that are covered within AVA.
