Abstract An electrostatic gyrokinetic guiding‐centre particle code is described where electrons and ions are simultaneously followed in the edge region. Full f technique is used for particle sampling and loading to allow efficient treatment of strong time variation in the collisional edge bulk plasma. Both the gyrokinetic ion polarization term and the implicit electron term in the quasi‐neutrality condition are determined based on the full‐f sampling for both electrons and ions. Issues relevant for the SOL modeling like recycling, heat source, and boundary conditions for plasma/wall interaction are discussed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
