A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…

Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams
B. Lee, B. Kim, P. Adrich +35
CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…

High-precision beam profile measurement with a microchannel-plate detector in the high magnetic field of the WISArD experiment
S. Lecanuet, X. Fléchard, P. Alfaurt +23
We present the development and characterization of a compact low-energy ion beam diagnostic for the WISArD (Weak Interaction Studies with Decay) experiment at IS…
