Using IPF-FDMC full wave code as a synthetic reflectometer for studying micro-instabilities computed by ORB5 — •Francesco Carpanese, Alessandro Biancalani, Alf Koehn, and Omar Maj — Max-Planck-Institut für Plasmaphysik Boltzmannstraße 2 D-85748 Garching

The gyro-kinetic codes have reached good maturity in simulating plasma electromagnetic nonlinear micro-instabilities which are responsible for turbulent transport. Validating these codes, such as ORB5, towards experiments requires to be able to reproduce data from diagnostics which detect the micro-instabilities characteristics. The reflectometer in particular is a valuable solution to measure density perturbation and turbulent spectrum near the cut-off of the injected wave [1]. A synthetic reflectometer, to be coupled to the gyro-kinetic code, is therefore needed for simulating and interpreting the experimental diagnostic. A new full-wave code is under development, taking advantage of a novel algorithm. At the same time the 2D finite difference IPF-FDMC code has been coupled to ORB5 to simulate a reflectometer (see also [2]).
