Electron Plasmas Cooled by Cyclotron-Cavity Resonance
A. P. Povilus, N. D. DeTal, L. T. Evans +10
We observe that high-Q electromagnetic cavity resonances increase the cyclotron cooling rate of pure electron plasmas held in a Penning-Malmberg trap when the electron cyclotron fr…
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…
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…
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…
