Highly focusing optics are used to mainly generate excess charge carriers in a small volume (approximately 1μm × 1μm × 20μm) around the focal point of the laser beam, which enables a resolution in all three spatial directions. The setup was used to study plasma effects in a PIN sensor, and the gain reduction mechanism in a 300μm thick LGAD sensor. Furthermore, the impact of diffusion on the gain reduction mechanism was modeled and employed towards the data. | Descripción: | Trabajo presentado al 40th RD50 Workshop on Radiation hard semiconductor devices for very high luminosity colliders, celebrado del 21 al 24 de junio de 2022 en el CERN (Zurich). | URI: | http://hdl.handle.net/10261/280069 |
