A large scale prototype for a SiW electromagnetic calorimeter for a future linear collider - EUDET Module

The CALICE collaboration is preparing large scale prototypes for highly granular calorimeters for detectors to be operated at a future linear electron positron collider. Currently a prototype of a SiW electromagnetic calorimeter will be assembled which in terms of dimensions and layout meets already most of the requirements given by the linear collider physics program and hence the detector design. In particular the front end electronics will be embedded into the layer structure of the calorimeter and have to fit within alveolar layers with less than 1 cm in height. In this contribution the design of the prototype is presented and the steps towards its realisation will be presented.
