Session 2: Planar Sensors
- Giovanni Calderini (Centre National de la Recherche Scientifique (FR))
Upgrades to existing particle physics detectors as well as future experiments in high-energy physics will continue to employ silicon sensors as central tracking elements, with an ever larger area covered by the silicon sensors. Already now, the sensors are a main cost driver. In addition, they are available from only a very small number of manufacturers in the quantities required. Therefore,...
The hybrid pixel detectors of the ATLAS and CMS experiments will be replaced for the operation at the HL-LHC in 2026. To maintain the tracking performance, the surface area of the future detectors will significantly increase while the pixel pitch decreases.
An attractive option for the production of the pixel sensors in such large area detectors is the utilization of a CMOS processing line....
During investigations of the signal composition in silicon strip sensors, that were irradiated and annealed until the occurrence of charge multiplication, it was observed that charge carriers created previously have effects on the subsequent signal. This lead to the conclusion that drifting charge left the sensor in a meta-stable state.
Using the Edge- and Top- Transient Current technique the...
With the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), the Compact Muon Solenoid (CMS) experiment is foreseen to collect an integrated luminosity of 3000 or even 4000 fb$^{-1}$. This comes with up to 200 proton-proton collisions per bunch crossing and correspondingly a high multiplicity of particle tracks. For 3000 fb$^{-1}$, the upgraded CMS Inner Tracker will have to...
The charge collection of three $150 \; \mu \text{m}$ thick $\text{n}^+\text{p}\text{p}^+$ pad diodes has been scanned along the diode thickness using a $4.2 \; \text{GeV}$ electron beam at the DESY II beam test facility. The electron beam enters from the sensor edge and its position along the edge was reconstructed by three planes of a EUDET-type telescope. Compared to the conventional...
