Abstract

The measurement of the plasma current is of paramount importance for controlling the plasma in tokamak discharges. FOCS (fibre optic current sensor) technology has already been proposed to perform such a measurement. During ITER operation, the vessel and the sensing fibre will be subject to vibrations and therefore to time varying extra parasitic birefringence. In this paper we propose to simulate the effects of vibrations on the measurement of the plasma current using the FOCS approach in ITER environment and to quantify the resulting inaccuracy.
