Azimuthal distribution of divertor plasma fluxes in an ℓ = 3 stellarator and torsatron

A multicontact probe placed near the wall has been used to study the distribution of the divertor fluxes over the minor azimuth in stellarator and torsatron regimes of the Saturn machine. It has been found that the plasma flux towards the outer part of the torus is much higher than the flux measured...

Description
Summary:A multicontact probe placed near the wall has been used to study the distribution of the divertor fluxes over the minor azimuth in stellarator and torsatron regimes of the Saturn machine. It has been found that the plasma flux towards the outer part of the torus is much higher than the flux measured along the direction to the inner part. The plasma fluxes are localized in the vicinity of the apexes of the magnetic surfaces and their azimuthal width near the wall does not exceed 1/18th of the vacuum chamber circumference.
