Description	Tunelová sonda je nový druh Langmuirovy sondy pro okrajovou oblast plazmatu na tokamacích. Dvou dimenzionální kinetická analýza rozložení iontového proudu na konkávním vodiči je použita pro kalibraci sondy pro rychlé měření iontového toku a elektronové teploty. Byl nalezen kvalitativní souhlas s měřením pomocí Langmuirovy sondy, ale elektronová teplota daná tunelovou sondou je několikrát menší. Tato neshoda muže být způsobena buď sekundární emisí elektronů ne přítomností supratermálních elektronů. (cs) The tunnel probe is a new kind of Langmuir probe for use in the tokamak scrape-off layer. Two – dimensional kinetic analysis of the ion current distribution on the concave conductors is used to calibrate the probe for making fast dc measurements of ion flux and electron temperature. Qualitative agreement with classical Langmuir probe measurements is found, but the electron temperature given by the tunnel probe is several times lower. This discrepancy can be caused by secondary electron emission, or the presence of suprathermal electrons. Strong reduction of ion flux and electron temperature fluctuations is observed during electrode biasing. The tunnel probe is a new kind of Langmuir probe for use in the tokamak scrape-off layer.
