The clogging deposits are mainly composed of magnetite (Fe$_3$O$_4$). With tracer injection ($^{59}$Fe) a nondestructive estimation of the deposit rates and the measure of the kinetics of deposition become possible. The aim of the gamma measurement is to be able to follow the deposition kinetics during the test phase under nominal conditions and to determine the influence of the hydraulic and chemistry parameters on this deposit.
