Aspects of the SID Detector Design for the International Linear Collider

The SiD (Silicon Detector) is one of four detector concepts being studied for the proposed International Linear Collider. The SiD is a compact, highly granular detector, that is designed to provide excellent jet energy resolution when used with particle flow algorithms. The high granularity is also advantageous for analysis of final states with tau leptons. In addition, its compact design allows for a large magnetic field that can mitigate the expected machine backgrounds allowing the first layer of the vertex detector to be close to interaction region. In this talk special emphasis will be given to two of the SiD subsystems, the electromagnetic calorimeter based on a silicon-tungsten calorimeter with integrated electronics and the Chronopixel option for the vertex detector. The electromagnetic calorimeter allows for very good separation of photons from charged particles. The Chronopixel vertex detector is designed to operate well in a high background environment.
