Abstract
For future high luminosity LHC experiments it will be important to develop new detector systems with increased space and time resolution and also better radiation hardness in order to operate in high luminosity environment. A possible technology which could give such performances is 3D silicon detectors. This work explores the possibility of a pixel geometry by designing and simulating different solutions, using Sentaurus Tecnology Computer Aided Design (TCAD) as design and simulation tool, and analysing their performances. A key factor during the selection was the generated electric field and the carrier velocity inside the active area of the pixel.
Highlights
In future high luminosity LHC (HL-LHC) experiments planned over the 10 years, the number of collisions per unit of time is expected to increase by more than a factor of 2 [1]
This work explores the possibility of a pixel geometry by designing and simulating different solutions, using Sentaurus Tecnology Computer Aided Design (TCAD) as design and simulation tool, and analysing their performances
A new approach to improve especially the time resolution is to use threedimensional (3D type) detectors. 3D Detectors are solid state devices introduced for the first time by Sherwood Parker during the nineties [2] and have been used increasingly in particle physics
Summary
In future high luminosity LHC (HL-LHC) experiments planned over the 10 years, the number of collisions per unit of time is expected to increase by more than a factor of 2 [1]. This will make possible to study rare phenomena and extend the knowledge of fundamental interactions. Their products and the interaction processes in these extreme conditions, detectors with very high space and time resolution will be needed (less than 100 μm in space and 100 ps in time).
