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…

Injection and capture of antiprotons in a Penning-Malmberg trap using a drift tube accelerator and degrader foil

C. Amsler, H. Breuker, M. Bumbar +33

The Antiproton Decelerator (AD) at CERN provides antiproton bunches with a kinetic energy of 5.3 MeV. The Extra-Low ENergy Antiproton ring at CERN, commissioned at the AD in 2018,…

Upgrade of the positron system of the ASACUSA-Cusp experiment

A. Lanz, C. Amsler, H. Breuker +35

The ASACUSA-Cusp collaboration has recently upgraded the positron system to improve the production of antihydrogen. Previously, the experiment suffered from contamination of the va…

Slow positron production and storage for the ASACUSA-Cusp experiment

D. J. Murtagh, C. Amsler, H. Breuker +35

The ASACUSA Cusp experiment requires the production of dense positron plasmas with a high repetition rate to produce a beam of antihydrogen. In this work, details of the positron p…

A compact low energy proton source

A. Weiser, A. Lanz, E. D. Hunter +3

A low energy proton source for non-neutral plasma experiments was developed. Electrons from a hot filament ionize H gas inside a geometrically compensated Penning trap to produ…
