Design and Performance of a Novel Low Energy Multi-Species Beamline for the ALPHA Antihydrogen Experiment
C. J. Baker, W. Bertsche, A. Capra +47
The ALPHA Collaboration, based at the CERN Antiproton Decelerator, has recently implemented a novel beamline for low-energy ( 100 eV) positron and antiproton transport be…
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…
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…
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…
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…
