Development of LGAD sensors at FBK

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2022
The High Luminosity upgrade of the Large Hadron Collider highlighted the need for a time-tagging of tracks with a precision of tens of picoseconds. This requirement motivated the development of radiation hard silicon sensors dedicated to the time-of-interaction measurement of minimum ionizing particles.

Radiation Tolerance of Proton-Irradiated LGADs

IEEE Transactions on Nuclear Science, 2018
Low gain avalanche detectors (LGADs), silicon sensors with intrinsic charge amplification, are being considered as a possible technology for tracking and timing in the high luminosity upgrade of the CERN Large Hadron Collider. In order to work in such an environment, LGADs must be sufficiently radiation hard.

Neutron detection with fast-timing LGAD

2019 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2019
The detection of neutrons with precise timing, in the orders of a few tens of ps, has several scientific applications, for example in the measurement of the fast neutron flux in space. We illustrate the response of two different sensors, based on Low Gain Avalanche Detector (LGAD) technology, to fast neutrons generated by a Deuterium-Tritium (DT ...

Trench-Isolated Low Gain Avalanche Diodes (TI-LGADs)

IEEE Electron Device Letters, 2020
We present a novel design of fine segmented low gain avalanche diodes (LGAD) based on trench-isolation technique. The proposed design reduces the width of the no-gain inter-pad region down to less than $10~\mu \text{m}$ , from the 20- $80~\mu \text{m}$ of the current LGAD technology, enabling the production of sensors with small pixel pitch ...

Ghosts in irradiated trench isolated LGADs

Journal of Instrumentation
Abstract In this paper we present the results from the study on the self-induced (ghost) signal observed in the neutrons irradiated trench-isolated Low Gain Avalanche Diodes (TI-LGADs). This is extension of the previous research on non-irradiated TI-LGADs where an extraordinary large signal was generated without external ...
