Plasma probes are well established diagnostic tools. They are not complicated, relatively
easy to construct and to handle. The easiest and fastest accessible parameter is their …

As in many of today's tokamaks, plasma start-up in ITER will be performed in limiter
configuration on either the inner or outer midplane first wall (FW). The massive, beryllium …

Time delay estimation methods (TDE) are well-known techniques to investigate poloidal
flows in hot magnetized plasmas through the propagation properties of turbulent structures …

The linear plasma generator Magnum-PSI was designed for the study of plasma–surface
interactions under relevant conditions of fusion devices. A key factor for such studies is the …

A series of discharges in hydrogen were performed in two experimental sessions. The
vessel was not conditioned before the first session, while inductive heating of the vessel and …

This paper describes a new filamentary probe recently introduced on the COMPASS
tokamak. It allows the measurement of electrostatic and magnetic properties of the filaments …

Thanks to my colleagues in the institute. The technicians for taking care of the tokamak,
without them, the experiments would be infeasible. My colleagues, mainly Honza Horácek …

The ion saturation current and floating potential are measured with high temporal (1 µs) and
spatial (2.5 mm) resolutions at the plasma edge of the CASTOR tokamak by two poloidally …

The ball-pen probe (BPP) is used for direct plasma potential measurements in magnetized
plasma. The probe can adjust the ratio of the electron and ion saturation currents I sat−/I sat+ …

The tunnel probe is a concave Langmuir probe designed to operate in strongly magnetized
plasma. Due to its shape, the tunnel probe is immune to sheath expansion effects and thus …
