The Compact Muon Solenoid (CMS) experiment is expected to collect an integrated luminosity of 3000 or even 4000fb^-1 in the ultimate scenario during the High Luminosity phase of the Large Hadron Collider (HL-LHC). This scenario comes with a high number of collisions per bunch crossing, and in turn, a high level of radiation for the inner layer of the CMS tracker. The simulations estimate a...
The Vertex Locator (VELO), surrounding the interaction region of the LHCb experiment, reconstructs the collision points (primary vertices) and decay vertices of long-lived particles (secondary vertices). The upgraded VELO will be composed of 52 modules placed along the beam axis divided into two retractable halves. The modules will each be equipped with 4 silicon hybrid pixel tiles, each...
The high integration density of Monolithic Active Pixel Sensors (MAPS), with silicon sensor and readout electronics implemented in the same device, allows very thin structures with strongly reduced material budget. Thicknesses of O(50um), values at which silicon chips become flexible, are readily used in many applications. In addition, MAPS can be produced in sensors of wafer size by a process...
MALTA is a novel monolithic active pixel CMOS sensor chip designed in TowerJazz 180nm imaging technology which targets radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have been investigated and have resulted in radiation hardness up to 2e15 n/cm2 with time resolution below 2 ns. Further improvements to detector efficiency have...
