Abstract

A rotating and sapping (radially fast moving) electrical double probe has been developed for implementation at the tokamak TEXTOR 94. This new diagnostic system allows to measure a large number of parameters in the edge plasma. It consists of the TEXTOR interface, the highly flexible vacuum chamber, the rotating probe system and the linear drive unit. The motors to drive the rotation and the slow and fast displacements are computer controlled for operation during the discharges
