Interferometry is the primary density control diagnostic for large-scale fusion devices, including ITER and DEMO. In this paper we present a ray tracing simulation based on TRAVIS accounting for relativistic effects. The study shows that measurements will over-estimate the plasma density by as much as 20°. In addition, we present a measurement geometry, which will enable vertical position control during the plasma’s ramp-up phase when gap-reflectometers and neutron cameras are still blind.
