 note = {"ECRH-driven transport of suprathermal electrons is studied in non-axisymmetric plasmas using a new Monte Carlo simulation technique in 5D phase space. Two different phases of the ECRH-driven transport of suprathermal electrons can be seen; the first one is a rapid convective phase due to the direct radial motion of trapped electrons and the second one is a slower phase due to the collisional transport. The important role of the radial transport of suprathemal electrons in the broadening of the ECRH deposition profile in W7-AS is clarified. The ECRH driven flux is also evaluated and put in relation with the ""electron root"" feature recently observed in W7-AS. It is found that, at low collisionalities, the ECRH driven flux due to the suprathermal electrons can play a dominant role in the condition of ambipolarity and, thus, the observed ""electron root"" feature in W7-AS is thought to be driven by the radial (convective) flux of ECRH generated supratherrnal electrons. The possible scenario of this ""ECRH-driven electron root"" is considered in the LHD plasma.                 .."},
