Abstract

The tunnel probe is a new kind of Langmuir probe for use in the tokamak scrape-off layer. It provides simultaneous measurements of electron temperature and parallel ion current density with high frequency at the same point in space. We describe ongoing work to characterise the ion flows within the probe, and to calibrate the diagnostics using 2D kinetic simulations.

This paper was presented at the 5th Workshop "Role of Electric Fields in Plasma Confinement and Exhaust", Montreux, Switzerland, June 23-24, 2002
