Studies of the SiD Silicon-Tungsten Calorimeter

SiD is a detector proposed for the e+e- International Linear Collider (ILC) with a silicon-tungsten sampling electromagnetic calorimeter (ECal). SiD at the ILC will measure the properties of the Higgs boson and top quark with precision beyond the capabilities of the LHC, and search for discoveries of new physics. The ECal boasts extremely high granularity that can separate electromagnetic showers even in busy environments of high energy jets. This is achieved with layers of silicon detectors containing 13 mm$^2$ pixels embedded in thin gaps ($\sim$ 1 mm) between tungsten alloy plates, creating a small but robust detection component. We present the results of simulation studies of the proposed calorimeter with emphasis on the gapless overlap between calorimeter modules. These studies build on the efforts of colleagues in the SiD Optimization group.
