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,…

A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios

M. J. Borchert, J. A. Devlin, S. E. Erlewein +20

The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter…

Ultra thin polymer foil cryogenic window for antiproton deceleration and storage

B. M. Latacz, B. P. Arndt, J. A. Devlin +21

We present the design and characterisation of a cryogenic window based on an ultra-thin aluminised PET foil at T < 10K, which can withstand a pressure difference larger than 1bar a…

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…
