Optimizing Antihydrogen Production via Slow Plasma Merging
E D Hunter, M Bumbar, C Amsler +29
We measure the time-dependent temperature and density distribution of antiprotons and positrons while slowly combining them to make antihydrogen atoms in a nested Penning-Malmberg…
Measured Properties of an Antihydrogen Beam
E. D. Hunter, M. Bumbar, C. Amsler +29
We report a factor of increase in the antihydrogen beam intensity downstream of ASACUSA's Cusp trap: atoms detected per -minute run. The beam contains many Rydberg…
Towards a Study of Low Energy Antiproton Annihilations on Nuclei
Viktoria Kraxberger, Marcus Bumbar, Angela Gligorova +30
A study of antiproton annihilations at rest on thin solid targets is underway at the ASACUSA facility, which now features a dedicated beam line for slow extraction at 250 eV. The e…
Antiproton annihilation at rest in thin solid targets and comparison with Monte Carlo simulations
Claude Amsler, Horst Breuker, Marcus Bumbar +33
The mechanism of antiproton-nucleus annihilation at rest is not fully understood, despite substantial previous experimental and theoretical work. In this study we used slow extract…
