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…
CERN AD/ELENA Antimatter Program
R. Caravita, A. Cridland Mathad, J. S. Hangst +6
The CERN AD/ELENA Antimatter program studies the fundamental charge, parity, time (CPT) reversal invariance through high-precision studies of antiprotons, antihydrogen, and antipro…
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,…
