Impact of Neutron Irradiation on LGADs with a Carbon-Enriched Shallow Multiplication Layer: Degradation of Timing Performance and Gain

Autor: Ramos, E. Navarrete, Duarte-Campderros, J., Fernández, M., Gómez, G., González, J., Hidalgo, S., Jaramillo, R., del Árbol, P. Martínez Ruiz, Moll, M., Quintana, C., Sikdar, A. K., Vila, I., Villegas, J.

In this radiation tolerance study, Low Gain Avalanche Detectors (LGADs) with a carbon-enriched broad and shallow multiplication layer were examined in comparison to identical non-carbonated LGADs. Manufactured at IMB-CNM, the sensors underwent neutro
