Development of multichord ion Doppler spectroscopy system for toroidal flow measurement of field-reversed configuration

December 2022 | K. Araoka | Review of Scientific Instruments | Paper

A double-chord ion Doppler spectroscopy (IDS) system was developed to measure the ion temperature and flow velocity of field-reversed configuration (FRC) plasmas in the FRC amplification via a translation-collisional merging (FAT-CM) device.

Ion kinetic effects and instabilities in the plasma flow in the magnetic mirror

November 2022 | M. Jimenez | Physics of Plasmas | Paper

Kinetic effects in plasma flow due to a finite ion temperature and ion reflections in a converging–diverging magnetic nozzle are investigated
with collisionless quasineutral hybrid simulations with kinetic ions and isothermal Boltzmann electrons.

Whose line is it anyway? A self-training spectral line identification code for plasma physics experiments

November 2022 | M. Tobin | Journal of Applied Physics | Paper

The process of associating spectral peaks in emission radiation data with particular charge states of specific elements is a common task in
the field of plasma diagnostics in both laboratory and astrophysical settings.
