Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The ball‐pen probe is an innovative electric probe for direct measurements of plasma potential in magnetised hot plasma. This probe is based on the Katsumata probe concept. The ball‐pen probe can adjust the ratio <italic>I⁻_sat</italic><italic>I⁺_sat</italic> of the electron and ion saturation currents to be equal to one causing the ball‐pen probe characteristics to become symmetric. If this is achieved, the floating potential of the ball‐pen probe is equal to the plasma potential. We show the application of a ball‐pen probe in two low‐temperature magnetised plasma devices and in torsatron TJ‐K (© 2013 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)</p> </abstract>
