SHEFFIELD, F.  and  FARENGO, R.. SIMULATION OF NEUTRAL BEAMINJECTIONIN POSITIVE AND NEGATIVE TRIANGULARITY TOKAMAKS. An. AFA [online]. 2023, vol.34, n.4, pp.4-4. ISSN 0327-358X.  http://dx.doi.org/10.31527/analesafa.2023.34.4.97.

In this paper the dynamics of high energy charged particles in negative and positive triangularity tokamaks is studied through the simulation of a neutral beam inyection on analytical MHD equilibria using the exact orbit code FOCUS. It is observed that the negative triangularity configuration presents fewer losses of non-thermal particles, and an energy deposition more localized than its counterpart.

Keywords : plasma; tokamak; triangularity; FOCUS.
