Silicon Detectors for Future Experiments – RD50 Status Report / Baselga, Marta (Dortmund U.) /RD50 Collaboration
In 2001 the Large Hadron Collider (LHC) and High Luminosity Large Hadron Collider (HL-LHC) were facing the challenging construction of experiments that have to withstand radiation levels never dealt with before in a particle detector. The innermost tracking layers, closest to the beam, are expected to reach an instantaneous luminosity of 7.5 × 10$^{34}$ cm$^{-2}$s$^{-1}$, being the result of 200 simultaneous proton-proton interactions per bunch crossing, and fluence levels of 2×10$^{16}$ n$_{eq}$/cm$^2$.

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.
