Advanced Imaging Calorimeters Development for SiD and Linear Collider Physics

This report presents the development of imaging calorimeters designed for the SiD flavor lepton collider. Presented at the Linear Collider Physics School in 2009, the work outlines requirements such as finely segmented readouts, cost-effective solutions, and technologies suitable for high magnetic fields. Key topics include the use of Resistive Plate Chambers (RPC) and Gas Electron Multipliers (GEM), testing in beam facilities, and strategies for effective data analysis and offline processing. The plans for future simulations, construction, and calibration are also highlighted.
