Abstract
The Monte Carlo guiding center (GC)-following code ASCOT has been upgraded with the full-orbit-following capability. This is utilized only near the vessel walls in order to simulate diagnostics with characteristic lengths on the order of the Larmor radius. The option to switch more generally, near the turning points of the particle, from the GC integration to full-orbit integration and back is also discussed.
