Silicon Sensors for Experiments in High Energy Physics

摘要

2.1 Introduction High energy physics (HEP) is probing the nature of matter. With large accelerators new particles are generated and huge detection systems identify the type and properties of those to challenge predictions of particle physics theories. The measurements agree very well with current theories, but more accurate measurements or detection of very rare events can help to identify the best descriptions of our universe. That pushes the acceleration systems to higher energy and luminosity. High luminosity comes with a large number of simultaneous tracks to be distinguished and a very harsh radiation environment. The detection systems closest to the interaction points are tracking and vertexing systems, which mainly rely on silicon sensors as sensitive elements and are strongly affected by increasing luminosity.
