Day 2 - Session 3: Avalanche Based Sensors

The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2s−1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High...
Low Gain Avalanche Detectors (LGADs) are a novel silicon sensor technology being developed to design full 4D trackers able to measure precisely both spatial and temporal coordinates. The first deployment of this technology will be in the ATLAS and CMS timing layers at the High Luminosity LHC where, by adding fast timing information to each crossing track, they will allow to better separate...
The next generation of high-energy and high-intensity hadron colliders for particle physics will require tracking detectors able to efficiently record charged particles in harsh radiation environments, where expected fluences exceed 10$^{17}$ particles/cm$^2$.
Recently, thin Low-Gain Avalanche Diodes (LGADs), with an active thickness of $\sim$ 50 $\mu m$, have proven their ability to...
Following up and finalizing the developments of former RnD projects and studies (INFN-funded TimeSPOT, Falaphel, Scaltech28 projects), The IGNITE project plans to implement an integrated system module, comprising sensor, electronics, and fast readout, specifically aimed at 4D-tracking. System pixels are required to have pitch around 50 µm and time resolution below 30 ps. In this paper we...
