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…
Cold neutral atoms via charge exchange from excited state positronium: a proposal
W. A. Bertsche, M. Charlton, S. Eriksson
We present a method for generating cold neutral atoms via charge exchange reactions between trapped ions and Rydberg positronium. The high charge exchange reaction cross section le…
Investigation of two-frequency Paul traps for antihydrogen production
Nathan Leefer, Kai Krimmel, William Bertsche +5
Radio-frequency (rf) Paul traps operated with multifrequency rf trapping potentials provide the ability to independently confine charged particle species with widely different char…
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…
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…
