This work reports on Total Ionizing Dose (TID) assessment on off-the-shelf LVDS links that will be used for the new trigger and readout system of the ATLAS muon barrel spectrometer within the HL-LHC program. We developed an experimental setup that allows to investigate TID effects on the currents drawn by the devices under test and on their signal integrity, including variations in amplitude, rise/fall time, and bit error rate. No significant variations of these quantities has been observed after integrating the ATLAS target dose of 84.6 Gy. In order to investigate high-dose effects, the irradiation has been extended up to 15.4 kGy. No post-annealing effects were observed. These results complement existing literature, proving the robustness of off-the-shelf LVDS links for the ATLAS environment.

Abstract
This work reports on Total Ionizing Dose (TID) assessment on off-the-shelf LVDS links that will be used for the new trigger and readout system of the ATLAS muon barrel spectrometer within the HL-LHC program. We developed an experimental setup that allows to investigate TID effects on the currents drawn by the devices under test and on their signal integrity, including variations in amplitude, rise/fall time, and bit error rate. No significant variations of these quantities has been observed after integrating the ATLAS target dose of 84.6 Gy. In order to investigate high-dose effects, the irradiation has been extended up to 15.4 kGy. No post-annealing effects were observed. These results complement existing literature, proving the robustness of off-the-shelf LVDS links for the ATLAS environment.File | Dimensione | Formato | |
