Comparison of Emissive and Plugged Probes DC Plasma Potential Measurements in a Magnetised Plasma

摘要

Measurements of DC plasma potential profile with emissive and plugged probe were carried out for different experimental conditions in the Simple Magnetised Torus Devices BLAAMANN and TEDDI. The comparison of the data shows, that after a proper check of the probe alignment, the plugged probe can be an durable and easy to use alternative.
