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…
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…
Physics with Trapped Charged Particles
Martina Knoop, Niels Madsen, Richard C. Thompson
Ion traps, which were first introduced in the late 1950s and early 1960s, have established themselves as indispensable tools in many areas of physics, chemistry and technology. Thi…
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…
