Adaptable platform for trapped cold electrons, hydrogen and lithium anions and cations
Levi O. A. Azevedo, Rodolfo J. S. Costa, Wania Wolff +4
Cold cations, electrons and anions are ubiquitous in space, participate in star formation chemistry and are relevant to studies on the origin of molecular biology homochirality. We…
Confinement of antihydrogen for 1000 seconds
ALPHA Collaboration, G. B. Andresen, M. D. Ashkezari +36
Atoms made of a particle and an antiparticle are unstable, usually surviving less than a microsecond. Antihydrogen, made entirely of antiparticles, is believed to be stable, and it…
Antihydrogen formation dynamics in a multipolar neutral anti-atom trap
G. B. Andresen, W. Bertsche, P. D. Bowe +33
Antihydrogen production in a neutral atom trap formed by an octupole-based magnetic field minimum is demonstrated using field-ionization of weakly bound anti-atoms. Using our uniqu…
A novel antiproton radial diagnostic based on octupole induced ballistic loss
G. B. Andresen, W. Bertsche, P. D. Bowe +35
We report results from a novel diagnostic that probes the outer radial profile of trapped antiproton clouds. The diagnostic allows us to determine the profile by monitoring the tim…
Compression of Antiproton Clouds for Antihydrogen Trapping
G. B. Andresen, W. Bertsche, P. D. Bowe +33
Control of the radial profile of trapped antiproton clouds is critical to trapping antihydrogen. We report the first detailed measurements of the radial manipulation of antiproton…
Towards Antihydrogen Confinement with the ALPHA Antihydrogen Trap
M. C. Fujiwara, G. Andresen, W. Bertsche +32
ALPHA is an international project that has recently begun experimentation at CERN's Antiproton Decelerator (AD) facility. The primary goal of ALPHA is stable trapping of cold antih…
