Test Particle Transport in Tokamak Divertor Magnetic Field Geometry:
Joint CNPS-DTT project held remotely at University College London during the 2021-2022 academic year.
Description: The project had the aim to establish a novel mathematical framework to
extended Boozer coordinates to the open flux surfaces regions of a tokamak, and to implement
this for the ORBIT code. A generalised analythical theory was successfully derived, and modified
numerically for realistic tokamak geometries. A new Python framework (BOSE-Equipe) has been written
to fully replace the legacy ORBIT-EQS workflow, and has been used to map Boozer coordinates in the
in the SOL for DTT and JET. The project's results are being expanded on, to allow for full particle
tracking in the divertor region as well, and a new orbit-tracing program based on adiabatic
invariants (NORBIT) is being developed. Link (pwd protected) to the
