SUMMARY:The Kinetic Plasma Physics Extension of the JOREK MHD Code: An Ove
 rview
DESCRIPTION:Minisymposium\n\nThe Kinetic Plasma Physics Extension of the J
 OREK MHD Code: An Overview\n\nSommariva, Huijsmans, Korving, Strien, Bogaa
 rts...\n\nJOREK is one of the world leading codes for the simulation of gl
 obal 3D time varying MHD instabilities of tokamak plasmas. The kinetic ext
 ension of the JOREK code will be discussed in this talk. It consists of a 
 collection of Monte-Carlo solvers capable to simulate the dynamics of plas
 ma particles evolving in 3D time-varying MHD fields including collision, r
 adiation, ionisation, recombination, charge exchange and sputtering effect
 s. The implemented particle models include relativistic and non-relativist
 ic full orbit and guiding center models which are solved using multi-purpo
 se or symplectic integrators. The kinetic and the fluid solvers are couple
 d projecting the particle distribution moments on the JOREK finite element
  representation. Code scalability is granted by a hybrid MPI-OpenMP parall
 elisation (a GPU-enabled version is in development). A wide range of inves
 tigations can be performed, such as: the generation of relativistic electr
 ons during plasma disruptions, the physics of neutral and impurity species
  in the divertor and scrape of layer regions, the dynamics of shattered pe
 llet injected material and the mutual interactions between energetic ions 
 and MHD instabilities. It is worth mentioning that a hybrid model with kin
 etic ions and adiabatic electrons (electrostatic at present) allows to stu
 dy ion temperature gradient instabilities in 3D plasma fields.\n\nDomain:
