LGAD and 3D as Timing Detectors / Ugobono, Sofia Otero (Barcelona, Inst. Microelectron.) /RD50 Collaboration
In view of the High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC), radiation tolerant silicon sensors are being developed in the framework of ATLAS, CMS, RD50 and other sensor R\&D; projects. The HL-LHC beam parameters and hardware configuration should enable the collider to reach a peak instantaneous luminosity of $5\times10^{34}\textrm{ cm}^{-2}\textrm{s}^{-1}$, and an integrated luminosity of 250 fb$^{-1}/\textrm{year}$ with the goal of 3000 fb$^{-1}$ after about 12 years of operation.

Radiation-tolerant Silicon Detectors for the LHC Phase-II Upgrade and Beyond: Review of RD50 Activities / Ott, Jennifer (Helsinki U. ; Helsinki U. of Tech.) /RD50 Collaboration
At the LHC Phase-II Upgrade foreseen for 2027, the particle densities and radiation levels will increase by roughly an order of magnitude compared to the present LHC conditions, and the silicon-based inner tracking systems have to be able to withstand fluences of up to 2$\times$ 16$^{16}$ n$_{eq}$/cm$^{2}$. To mitigate the increased pileup at the HL-LHC, dedicated timing detectors are employed.Within the CERN RD50 Collaboration, a large RD program has been underway for more than a decade across experimental boundaries to develop silicon sensors with sufficient radiation tolerance for HL-LHC tracking and timing detectors. [...]

Radiation damage in p-type EPI silicon pad diodes irradiated with protons and neutrons / Gurimskaya, Yana (CERN) ; Dias De Almeida, Pedro (CERN ; Cantabria U., Santander) ; Fernandez Garcia, Marcos (Cantabria U., Santander) ; Mateu Suau, Isidre (CERN) ; Moll, Michael (CERN) ; Fretwurst, Eckhart (Hamburg U.) ; Makarenko, Leonid (Belarus State U.) ; Pintilie, Ioana (Bucharest, Nat. Inst. Mat. Sci.)
In view of the HL-LHC upgrade, radiation-tolerant silicon sensors containing low-resistivity p-type implants or substrates, like LGAD or HV-CMOS devices, are being developed in the framework of ATLAS, CMS, RD50 and other sensor R&D; projects. These devices are facing a particular problem — the apparent deactivation of the doping due to the irradiation, the so-called acceptor removal effect. [...]

Development of RD50-MPW2: a high-speed monolithic HV-CMOS prototype chip within the CERN-RD50 collaboration / Zhang, Chenfan (Liverpool U. ; Fond. Bruno Kessler, Trento) ; Casse, Gianluigi (Liverpool U. ; Fond. Bruno Kessler, Trento) ; Massari, Nicola (Fond. Bruno Kessler, Trento) ; Vilella, Eva (U. Liverpool (main)) ; Vossebeld, Joost (U. Liverpool (main))
The CERN-RD50 collaboration has ongoing research to further develop monolithic High Voltage-CMOS (HV-CMOS) sensors in a 150 nm process for future particle physics experiments. As a part of this research programme, a test chip (RD50-MPW2) that implements new methodologies for low leakage current and fast and low-noise readout circuitry has been designed and submitted for fabrication.
