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…
Limit on the Electric Charge of Antihydrogen
A. Capra, C. Amole, M. D. Ashkezari +37
The ALPHA collaboration has successfully demonstrated the production and the confinement of cold antihydrogen, . An analysis of trapping data allowed a strin…
Antihydrogen and mirror-trapped antiproton discrimination: Discriminating between antihydrogen and mirror-trapped antiprotons in a minimum-B trap
C. Amole, G. B. Andresen, M. D. Ashkezari +35
Recently, antihydrogen atoms were trapped at CERN in a magnetic minimum (minimum-B) trap formed by superconducting octupole and mirror magnet coils. The trapped antiatoms were dete…
Towards Antihydrogen Trapping and Spectroscopy at ALPHA
Eoin Butler, Gorm. B. Andresen, Mohammad. D. Ashkezari +37
Spectroscopy of antihydrogen has the potential to yield high-precision tests of the CPT theorem and shed light on the matter-antimatter imbalance in the Universe. The ALPHA antihyd…
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…
Search For Trapped Antihydrogen
Gorm B. Andresen, Mohammad D. Ashkezari, Marcelo Baquero-Ruiz +39
We present the results of an experiment to search for trapped antihydrogen atoms with the ALPHA antihydrogen trap at the CERN Antiproton Decelerator. Sensitive diagnostics of the t…
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…
