Ball-pen probe - a useful tool for measuring the plasma potential in magnetized plasma

Abstrakt

Methods of direct measurement of the plasma potential and their significance for characterizing the scrape-off layer plasma in fusion devices are briefly discussed. Stress is given to description of the ball-pen probe and its use for plasma potential determination in a broad range of magnetized plasmas.
