In situ electromagnetic field diagnostics with an electron plasma in a Penning-Malmberg trap
C. Amole, M. D. Ashkezari, M. Baquero-Ruiz +37
We demonstrate a novel detection method for the cyclotron resonance frequency of an electron plasma in a Penning-Malmberg trap. With this technique, the electron plasma is used as…
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…
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…
Centrifugal separation and equilibration dynamics in an electron-antiproton plasma
G. B. Andresen, M. D. Ashkezari, M. Baquero-Ruiz +34
Charges in cold, multiple-species, non-neutral plasmas separate radially by mass, forming centrifugally-separated states. Here, we report the first detailed measurements of such st…
Alpha Antihydrogen Experiment
ALPHA Collaboration, M. C. Fujiwara, G. B. Andresen +37
ALPHA is an experiment at CERN, whose ultimate goal is to perform a precise test of CPT symmetry with trapped antihydrogen atoms. After reviewing the motivations, we discuss our re…
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…
