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…

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,…

Towards the formation of a positronium coherent beam

M. Sacerdoti, V. Toso, G. Vinelli +5

Positronium (Ps) has emerged as a promising test particle within the QUPLAS collaboration for investigating the gravitational effect. In this work, we present a novel approach to g…
