Abstract

We describe the synthetic diagnostics (SD) of the preliminary design of divertor neutron flux monitor (DNFM) dedicated for simulations of the neutron flux measurements in ITER. It is based on the technique developed for fast simulation of plasma evolution keeping the accuracy of comprehensive 3D Monte Carlo simulations. The developed technique is also applicable to simulations of diagnostics signals for a range of neutron and optical diagnostics in tokamak plasmas and enables fast simulations of the local radiation fields and diagnostic signals for arbitrarily distributed volumetric sources. The capabilities of the DNFM SD are demonstrated for simulations of the ITER baseline scenario.
