Session 9: LGAD (2)
- Giulio Pellegrini (Centro Nacional de Microelectrónica (IMB-CNM-CSIC) (ES))
The CMS MIP Timing Detector, proposed for the HL-LHC upgrade, will be instrumented with O(10) square meters of ultra-fast Silicon detectors (UFSD) in the forward region. These UFSDs are aimed at measuring the time of passage of each track with a precision of about 30 ps. In this presentation, the progress towards the development of this large area detector is reviewed, pointing out the current...
The radiation hardness of the gain layer is a main topic in the development of UFSD. The second UFSD production (UFSD2) by Fondazione Bruno Kessler (FBK) in Trento, in collaboration with University of Trento and National Institute of Nuclear Physics (INFN) in Torino, demonstrated a radiation hardness improvement in gain layer with co-implantation of Carbon.
In the third UFSD production (UFSD3)...
Low Gain Avalanche Detectors are a promising technology in the field of ultra fast timing detectors. Studies of the radiation hardness of LGADs have raised questions about the relation between the onset of multiplication and the depletion of the amplification layer.
To address these questions and to investigate the change of gain and the electric field after irradiation and annealing, LGADs...
A comprehensive radiation tolerance study of LGAD pad-like sensors manufactured at IMB-CNM and irradiated at CERN's PS-IRRAD proton facility up to a fluence of $3 \times 10^{15} n_{eq}/cm^2$ is presented here. Two different active thicknesses were studied: 35-microns and 50-microns; the effect of carbon co-implantation on the radiation tolerance was also investigated.
The building block LGAD...
In the past decade, hybrid silicon detectors with single photon counting readout have been a breakthough for several hard X-ray experimental techniques.
However, they still cannot be used for X-ray energies below 2 keV, since the electronic noise becomes comparable to the charge generated by single X-rays.
The amplification provided by LGAD sensors improves the signal-to-noise ratio and the...
