The ball-pen probe (BPP) [2–5] for direct measurements of the plasma potential Φpl was developed by Adamek et al. [6, 7] in the Institute of Plasma Physics in Prague. A combination of BPP and common Langmuir probe (LP) provides the value of the electron temperature Te by the difference between the plasma and floating potential Te =(Φpl – Vfl )/2.2 [4]. The BPP/LP head was mounted on the reciprocating midplane manipulator. Comparative measurements using probe diagnostics and edge/core Thomson scattering on COMPASS and ASDEX Upgrade are reported in the paper.
