Description	Předneseno na konf.:Annual Conference of Doctoral Students - WDS 2010 Prague,01.06.–04.06.2010,str.33-37,:Katsumata probe serves to measure the ion temperature in magnetized plasma According to the basic theory, when the collector is retracted in the tube, electrons with their small Larmor radii should not be able to reach it and the collector becomes sensitive to ions. However, experimental results show, that the electron shielding is in general inefficient, it only works in the case, when the potential of the collector is same as the potential of the inside surface of the tube.We have used full 3D Particle-In-Cell code with multigrid Poisson solver to simulate the plasma behavior in the vicinity of a model of the Katsumata probe. Potential structure at the entrance of the tunnel was identified. This structure produced ExB drifts which push electrons into the shielded space. Simulations revealed that electrons can penetrate inside the geometrical shadow in all studied Předneseno na konf.:Annual Conference of Doctoral Students - WDS 2010 Prague,01.06.–04.06.2010,str.33-37,:Katsumata probe serves to measure the ion temperature in magnetized plasma According to the basic theory, when the collector is retracted in the tube, electrons with their small Larmor radii should not be able to reach it and the collector becomes sensitive to ions.
