Collider experiments as the upcoming Phase II- LHC or the future circular collider (FCC) will increase the demands of the detectors used for tracking. In the FCC, sensors will not only face fluences of up to $1\times10^{17}~n_\mathrm{eq}/\mathrm{cm}^2$ , but also high pile-up scenarios. Therefore, sensors will be required that not only have a good spatial resolution and a very high radiation...
The ATLAS experiment is currently preparing for the High Luminosity Upgrade of the LHC.
An all-silicon Inner Tracker (ITk) that will replace the current ATLAS Inner Detector, is under development with a pixel detector surrounded by a strip detector. The strip system consists of 4 barrel layers and 6 EC disks. After completion of final design reviews in key areas, such as Sensors, Modules,...
The LHC machine is planning an upgrade program which will smoothly bring the luminosity to about $5-7.5\times10^{34}$cm$^{-2}$s$^{-1}$, to possibly reach an integrated luminosity of $3000-4500\;$fb$^{-1}$ by the end of 2039. This High Luminosity LHC scenario, HL-LHC, will require an upgrade program of the LHC detectors known as Phase-2 upgrade. The current CMS Outer Tracker, already running...
The ALICE collaboration is pursuing the development of a novel and
considerably improved vertexing detector called ITS3, to replace the
three innermost layers of the Inner Tracker System during the LHC Long
Shutdown 3.
The primary goals are to reduce the material budget to the
unprecedented value of 0.05% X_{0} per layer, and to place the first layer
at a radial distance of 18 mm from...
Within the RD50 Collaboration, a large and dedicated R&D program has been underway for more than two decades across experimental boundaries to develop silicon sensors with high radiation tolerance for Phase-II LHC trackers. Based on the success of this R&D, these trackers are now entering their construction phase. RD50 is continuing its mission to study silicon sensors for particle tracking,...
Low Gain Avalanche Detectors (LGADs) are thin silicon detectors with moderate internal signal amplification, providing time resolution as good as 17 ps for minimum ionizing particles. In addition, their fast rise time and short full charge collection time (as low as 1 ns) is suitable for high repetition rate measurements in photon science and other fields. However, a major limiting factor for...
Future collider experiments operating at very high instantaneous luminosity will greatly benefit in using detectors with excellent time resolution to facilitate event reconstruction. For the LHCb Upgrade2, when the experiment will operate at 1.5x10^34/cm/s, 2000 tracks from 40 pp interactions will cross the vertex detector (VELO) at each bunch crossing. To properly reconstruct primary vertices...
The success of the Belle II experiment in Japan relies on the very high instantaneous luminosity, close to 6x10^35 cm^-2 s^-1, expected from the SuperKEKB collider. The corresponding beam conditions generate large rates of background particles and creates stringent constraints on the vertex detector, adding to the physics requirements.
Current prospects for the occupancy rates in the present...
LHCb has recently submitted a physics case for an Upgrade II detector to begin operation in 2031. The upcoming upgrade is designed to run at instantaneous luminosities of $1.5\times 10 ^{34}cm^{−2} s^{−1}$, to accumulate a sample of more than 300 fb$^{−1}$. The LHCb physics programme relies on an efficient and precise vertex detector (VELO). Compared to Upgrade I, the data output rates,...
