Temporal characterisation of silicon sensors on Timepix3 ASICs

The timing performance of silicon sensors bump-bonded to Timepix3 ASICs is investigated, prior and after different types irradiation up $8 \times 10^{15} 1 \mathrm{\,Me\kern -0.1em V} \mathrm{ \,n_{eq}} {\mathrm{ \,cm}}^{-2}$. have been tested with a beam charged particles in two configurations, perpendicular almost parallel the incident beam. second approach, known as grazing angles method, shown be powerful method investigate not only charge collection, but also time-to-threshold properties function depth at which charges are liberated.
