Abstract
Abstract
Reciprocating probes are a classic and widespread tool for
the investigation of the edge and Scrape-Off Layer of magnetic
fusion plasmas. In the Wendelstein 7-X (W7-X) stellarator, the
Multi-Purpose Manipulator serves as a multi-user platform for
probe measurements of various kinds. This paper presents a review on
reciprocating probe operation during the first operation phase of
W7-X with a test divertor (2017–2018). It gives an overview of the
diverse zoo of probe heads and presents lessons learned about probe
operation in complex magnetic geometries, operation safety, and
probe head design. A few examples of probe measurements with a focus
on unexpected observations are presented, e.g. indications for
supra-thermal electrons and the propagation of plasma perturbations
due to biased probes.
