Description
Timing resolution of LGAD sensors with different thicknesses, ranging from 45 down to 20 $\mu$m will be presented. The results are obtained through a $\beta$-source stimulus and electron beam test at the DESY facility. A timing resolution down to 16.6 ps has been reached by 20 $\ mum$-thick sensors, reduced to 12.2 ps by using the information from 2 different planes of 20 $\mu$m sensors. Irradiated sensors with a thickness of 30 $\mu$m have been investigated, up to a fluence of 2.5$\cdot$10$^{15}$ 1 MeV equivalent n/cm$^2$, demonstrating no degradation in timing resolution with irradiation up to the highest fluence.
