Session 2: Planar Sensors (1)
- Yoshinobu Unno (High Energy Accelerator Research Organization (JP))
The ATLAS Pixel detector has been operating since 2010 and consists of hybrid pixel modules where the sensitive elements are planar n-in-n sensors.
In order to investigate and predict the evolution of the depletion voltage and of the leakage current in the different layers, a fully analytical implementation of the Hamburg model was derived. The parameters of the model, describing the...
The silicon-based tracking detector systems in the HL-LHC upgrade will be exposed to highly adverse radiation conditions for more than a decade, without access options for service or repair. It is therefore imperative to understand and predict the long-term evolution of sensor properties, including the signal collection efficiency and the leakage current. In this context, we present a summary...
The ATLAS experiment will undergo around the year 2025 a replacement of the tracker system in view of the high luminosity phase of the LHC (HL-LHC) with a new 5-layer pixel system.
Thin n-in-p planar pixel sensors are promising candidates to instrument the new pixel system, thanks to the reduced contribution to the material budget and their high charge collection efficiency after irradiation....
