Abstract
A compact digital Si-W sampling electromagnetic calorimeter prototype using Monolithic Active Pixel Sensors (MAPS) with a granularity of \(30 \times 30\; \upmu \text {m}\) and a total depth of 28 \(X_{0}\) has been built and tested with beams. The test beam results demonstrate not only good energy linearity and reasonable energy resolution, but also a position resolution of better than 30 \({\upmu }\text {m}\). This precise position determination and the detailed knowledge of the electromagnetic shower shape obtained will provide the crucial capability for two-photon separation for the final design.
