Short project description

The main purpose of this PhD project is the development of a Fiber Optics Current Sensor (FOCS) prototype suitable for performing measurements in future thermonuclear fusion reactors, considering the ITER tokamak as the main application and with a demonstration of operation at WEST. The achievement of this task requires innovations in fiber-optics current sensing combined with the adaptation of the FOCS engineering design, making it suitable for the use during Burning Plasma eXperiments (BPX). Besides the optimization of a global FOCS simulation tool, particular scientific challenges to be addressed are the following

- the experimental study of the neutron and gamma radiation effect on the Verdet constant and on the radiation induced absorption of candidate fibers;

- the study of the effect of fiber bending and twist on the measurement accuracy and on the polarimetric scheme;

- the optimization and validation of the calibration.

The minimum diploma level of the candidate needs to be

Master of sciences , Master of sciences in engineering

The candidate needs to have a background in

Electromechanics , Physics , Optical fiber technology, Physics, knowledge of Optical fiber sensing is an advantage
