Towards The Capture And Spectroscopy Of Antiproton Annihilation Fragments In A Penning-Malmberg TrapHYBRID

The Antimatter Experiment: Gravity, Interferometry, Spectroscopy (AEgIS) at CERN's antimatter factory has achieved remarkable performance in trapping antiprotons for the pulsed creation of antimatter-bound systems, such as antihydrogen, to study the gravitational influence on antimatter. Currently, a new technique is being developed using the AEgIS infrastructure to synthesize antiprotonic atoms, where an antiproton (1836 times the mass of the electron) is captured in close orbits around the atomic nucleus. This synthesis, occurring inside a Penning-Malmberg trap, allows for novel studies in an ultra-high vacuum environment, such as capturing the highly charged nuclear fragments that result from the antiprotonic atom cascade and annihilation on the nuclear surface. The study of these fragments offers unique insight into the annihilation mechanism, nuclear structure properties, and provides a new tool to synthesize radioactive highly charged ions (HCIs) in a trapped environment. In this talk, I will describe the proof-of-principle studies and the ongoing efforts towards the development of this new technique.
