AI Article Synopsis

  • A new method for measuring toroidal velocity using Mach probes has been developed.
  • This technique employs conditional sampling, using density blobs as triggering events.
  • It allows for the reconstruction of time-resolved 2D profiles of key plasma parameters, including electron density and temperature, from a single measurement taken during each shot.

Article Abstract

A new method for toroidal velocity measurements with Mach probes is presented. This technique is based on the conditional sampling technique, the triggering events being density blobs. A reconstruction of the time resolved two-dimensional profile of electron density, electron temperature, plasma potential, and toroidal velocity is possible with a single point measurement on a shot-to-shot basis.
