Limitations from charge quantization on the parallel temperature diagnostic of nonneutral plasmas
Adrianne Zhong, Joel Fajans, Jonathan S. Wurtele
We develop a new algorithm to estimate the temperature of a nonneutral plasma in a Penning-Malmberg trap. The algorithm analyzes data obtained by slowly lowering a voltage that con…
Variational Principle for Spontaneous Wiggler and Synchrotron Radiation
A. E. Charman, J. S. Wurtele, G. Penn
Within the framework of a Hilbert space theory, we develop a maximum-``power'' variational principle (MPVP) applicable to classical spontaneous electromagnetic radiation from relat…
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…
Nonlinear dynamics of antihydrogen in magnetostatic traps: implications for gravitational measurements
Andrey Zhmoginov, Andrew Charman, Joel Fajans +1
The influence of gravity on antihydrogen dynamics in magnetic traps is studied. The advantages and disadvantages of various techniques for measuring the ratio of the gravitational…
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…
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…
