WG2 - Hybrid silicon sensors

Trench-isolated LGADs (TI-LGADs), developed at FBK, are devices in which pixelated LGAD pads are separated by physical trenches etched into the silicon substrate and filled with a dielectric material. Designed as an alternative to implant-based inter-pad isolation techniques (such as JTEs), this technology offers a significant reduction in dead regions, thereby mitigating fill-factor...

WG2 - Hybrid silicon sensors

The development of next-generation particle detectors capable of precise 4D tracking is crucial for future high-energy physics experiments. AC-LGAD have emerged as a leading technology to achieve excellent spatial and temporal resolution simultaneously. This report details the development and characterization of a new batch of AC-LGAD detectors fabricated by the University of Science and...

52. Stress Tests on Low Gain Avalanche Diodes and AC-coupled Low Gain Avalanche Diodes

WG2 - Hybrid silicon sensors

Devices with internal gain, such as Low Gain Avalanche Diodes (LGADs), demonstrate O(30) ps timing resolution, and they play a crucial role in High Energy Physics (HEP) experiments, among other applications. Similarly, resistive silicon devices, such as AC-coupled Low Gain Avalanche Diodes (AC-LGADs) sensors, achieve a fine spatial resolution while maintaining the LGAD’s timing resolution....

WG2 - Hybrid silicon sensors

Resistive Silicon Devices (RSDs), particularly AC-coupled Low Gain Avalanche Diodes (AC-LGADs), open the path of pico-second level space and time (4D) tracking in high-energy physics (HEP) experiments such as those at the Large Hadron Collider (LHC), Electron-Ion Collider (EIC), and future (lepton) colliders facilities. These sensors combine the fine spatial resolution of segmented detectors...

WG2 - Hybrid silicon sensors

Low Gain Avalanche Detectors (LGADs) are characterized by a fast rise time (~500ps) and extremely good time resolution (down to 17ps), and potential for a very high repetition rate with ~1 ns full charge collection. For the application of this technology to near future experiments such as e+e- Higgs factories (FCC-ee), the ePIC detector at the Electron-Ion Collider, or smaller experiments...

17. Properties of DC-RSD with different surface resistivities and pixel sizes

Nicolo Cartiglia (INFN Torino (IT))

WG2 - Hybrid silicon sensors

In this contribution, I will present new studies on the properties of DC-RSD. These sensors, manufactured at FBK, have been tested at 2 test beams at the DESY beam line. The performance of prototypes with different surface resistivities and pixel sizes will be presented. This study also focuses on the determination of the relationship between surface resistivity and pixel size, identifying a...

12. Advancements in Low-Gain Avalanche Diodes (LGADs) for the ALICE 3 timing layers

Francesca Carnesecchi (INFN e Laboratori Nazionali di Frascati (IT))

WG2 - Hybrid silicon sensors

The proposed ALICE 3 experiment requires outstanding Particle Identification (PID) based on Time-of-Flight (TOF), setting a highly ambitious timing resolution target of 20 ps. Achieving this goal necessitates intensive Research and Development (R&D) into next-generation silicon sensor technology for large-area systems.

Low-Gain Avalanche Diodes (LGADs) are primary candidates due to their...

22. Towards Active Edge Silicon Sensors Fabricated with Edge Ion Implantation And Microwave Anneal Activation

Andrew Donald Gentry (University of New Mexico (US))

11/11/2025, 17:28

WG2 - Hybrid silicon sensors

Silicon detectors typically require a large inactive region surrounding the sensitive region, to accommodate guard rings, which help maintain the electric field uniformity around peripheral pixels, and isolate high current generation due to defects at the physical edges of the detectors. Sensors with reduced inactive regions around their periphery are desirable for applications in high-energy...

WG2 - Hybrid silicon sensors

The preliminary characterisation of thin LGAD sensors on n-type substrate will be presented. Electrical performances from I-V and C-V measurements on the wafer will be shown, along with the gain behaviour using red and blue LEDs.
