Innovations in silicon detector technologies for next-generation experiments: Improving timing precision of LGADs for ALICE 3
/ Strazzi, Sofia (INFN, Bologna ; Bologna U.)
/ALICE Collaboration
In the dynamic realm of silicon detector advancements, a big challenge remains to unlock the full potential for realizing large-area systems, showcasing the extraordinary time resolution demanded by next-generation experiments. This proceeding provides an overview of the intensive R&D; program on Low Gain Avalanche Diodes (LGADs) in the context of the future ALICE 3 experiment at CERN, in Run 5 and 6, aiming to develop a 20-picosecond technology for the Time-Of-Flight detector.

(INFN, Turin) ; Margotti, A. (INFN, Bologna) ; Menzio, L. (INFN, Turin ; Turin U.) et al.
This paper describes the new concept of the double-LGAD. The goal is to increase the charge at the input of the electronics, keeping a time resolution equal or better than a standard (single) LGAD; this has been realized by adding the charges of two coupled LGADs while still using a single front-end electronics.

Microelectron.) et al.
Novel collider experiments demand an increased performance of the silicon detectors used, such as withstanding up to 1×1017neq/cm2 in unprecedented pile-up conditions and providing time resolution around 10ps. Currently, Low Gain Avalanche Diodes (LGADs) are the standard, achieving resolutions below 30ps. [...]

Results of the new MAPS-based ALICE inner tracker operations in the LHC Run 3
/ Ravasenga, Ivan (CERN)
/ALICE Collaboration
The new ALICE Inner Tracking System (ITS2), installed in ALICE in May 2021 during a major upgrade campaign, significantly enhances the resolution on the determination of the distance of closest approach to the primary vertex, the tracking efficiency at low transverse momenta, and the read-out rate capabilities with respect to the previous tracker. It is equipped with silicon Monolithic Active Pixel Sensors (MAPS) with a pixel size of 27 × 29 μm2, a spatial resolution of 5μm and it features a material budget of 0.36 % X0 (inner layers). [...]
