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…
Evaporative Cooling of Antiprotons to Cryogenic Temperatures
ALPHA Collaboration, G. B. Andresen, M. D. Ashkezari +37
We report the application of evaporative cooling to clouds of trapped antiprotons, resulting in plasmas with measured temperature as low as 9~K. We have modeled the evaporation pro…
The First Cold Antihydrogen
M. C. Fujiwara, M. Amoretti, C. Amsler +29
Antihydrogen, the atomic bound state of an antiproton and a positron, was produced at low energy for the first time by the ATHENA experiment, marking an important first step for pr…
