Abstract

We simulated electron motion in confronting divergent magnetic fields (CDMFs) using a Monte Carlo method. Fundamental plasma structure under a filtering effect of the separatrix of CDMFs was depicted. Hot spots of energy deposition into electrons were observed not only near the RF antenna but also near the equistrength surface of 2B <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ECR</sub> , where B <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ECR</sub> is the RF-resonant magnetic field strength.
