    AnnotationLangmuir probes are amongst the most versatile tools for plasma diagnostics for both magnetized and unmagnetized plasmas. Analysis of I–V characteristics measured by the probe can in principle yield values of electron temperature Te, floating potential Vfl and electron density ne as well as electron energy distribution function. However, correct values of these quantities
    can be determined only when all the instrumental effects on measured data are addressed. For magnetized plasma in the scrape-off layer of tokamak discharges, the prevalent influence is the sheath expansion due to presence of strong magnetic field. This effect is taken into account by introduction of fourth parameter to fit of the I–V curve [1].
