The high-luminosity upgrade of the LHC (HL-LHC) brings unprecedented requirements for precision bunch-by-bunch luminosity measurement and beam-induced background monitoring in real time. A key component of the CMS Beam Radiation Instrumentation and Luminosity detector system is a stand-alone luminometer, the Fast Beam Condition Monitor (FBCM), which is able to operate independently at all times with a triggerless asynchronous readout.

The FastRICH ASIC for the LHCb RICH enhancements / Keizer, F (CERN) /LHCb RICH Collaboration
The Ring-Imaging Cherenkov (RICH) detectors at LHCb have an excellent intrinsic time resolution due to the prompt Cherenkov radiation and focusing mirror optics. Novel RICH readout electronics, to be installed during the third Long Shutdown period (LS3) of the LHC, will introduce fast-timing information in the LHCb experiment. [...]

Development and prototype of a new luminometer for the ATLAS experiment during Run 3 and Run 4 of the LHC / Bruschi, Marco (INFN, Bologna)
The Beam Monitor for ATLAS (BMA) detector is an additional luminosity monitor for the ATLAS experiment, targeting the luminosity determination for the high luminosity phase of the Large Hadron Collider (HL-LHC). The detector is composed of small square pads with about 1 mm per side of Low Gain Avalanche Detector (LGAD) silicon sensors, intended to be placed in the ATLAS detector forward shielding at about 16m from the interaction point.

ALICE Inner Tracking System upgrade, ITS3: characterization of first chips fabricated in 65 nm CMOS technology / Trifirò, Antonio (Messina U. ; INFN, Catania) /ALICE Collaboration
The Inner Tracking System of ALICE (A Large Ion Collider Experiment) will undergo a major upgrade during the next Long Shutdown of the LHC aimed at enhancing the tracking capability [1]. In particular, the three innermost sectors of the current vertex tracker will be replaced by truly cylindrical layers produced by using curved (wafer-scale) silicon sensors thinner than 50 μm, based on monolithic active pixel structures realised in a 65 nm CMOS process.

ITS3: the ALICE Inner Tracking System upgrade / Sarritzu, Valerio (CERN ; Cagliari U. ; INFN, Cagliari) /ALICE Collaboration
The ALICE experiment at CERN is developing an upgrade to its vertexing detector in order to improve the impact parameter resolution at low transverse momenta, with a target timeline for installation during the third long shutdown of the LHC (2026–28). The concept consists in replacing the three innermost layers with wafer-scale monolithic active pixel sensors bent into truly cylindrical sensors wrapped around the beam pipe. [...]

The CMS Tracker performance in LHC Run 3 / Kello, Tomáš (INFN, Florence) /CMS Collaboration
The Tracker of the Compact Muon Solenoid (CMS) experiment is the largest silicon tracker ever built, with 1856 pixel and 15148 strip detector modules that provide accurate track reconstruction. Special challenges must be addressed in the Run 3 data-taking period such as the high instantaneous luminosity and the rapid changes due to module irradiation, particularly in the newly installed Layer 1 of the barrel pixel detector.

Radiation Hard Pixel Sensors for the Phase 2 Upgrade of the CMS Inner Tracker / Steinbrück, Georg (University of Hamburg) /The Tracker Group of the CMS Collaboration
The Inner Tracker (IT) of the Compact Muon Solenoid (CMS) experiment of the Large Hadron Collider at CERN will be upgraded for the High-Luminosity LHC (HL-LHC). The expected integrated luminosity at the end of the HL-LHC running phase is at least 3000 fb$^{-1}$, corresponding to a 1 MeV neutron equivalent fluence of $\Phi_{eq} = 2.6 \times 10^{16}$ cm$^{-2}$ and a total ionizing dose (TID) of 13 MGy at the innermost layer of the IT.All the layers of the IT (except for the innermost barrel layer) will be equipped with planar n$^+$-p pixel sensors with an active thickness of 150 $\mu$m and pixel sizes of 25 $\mu$m $\times$ 100 $\mu$m.The innermost barrel layer will feature 3D silicon sensors owing to their excellent radiation hardness and lower power consumption; it is foreseen to be exchanged at least once during HL-LHC operation.Planar and 3D prototype sensors were bump bonded to the CMS prototype chip (CROCv1), implemented in 65 nm CMOS technology.In an extensive qualification campaign, sensor-chip assemblies were tested in the lab and at the CERN and DESY testbeam facilities before and after proton irradiation up to $\Phi_{eq} = 2 \times 10^{16}$ cm$^{-2}$, exceeding the expected maximum fluences.In this paper, more recent measurements of the hit efficiency, spatial resolution, and noise studies are presented after proton irradiation at the CERN Proton Synchrotron (PS)up to $\Phi_{eq} = 1 \times 10^{16}$ cm$^{-2}$.For all parameters investigated, the results meet or exceed the CMS specifications.
