Abstract
In this paper we describe the DECAL Monolithic Active Pixel Sensor (MAPS) for digital electromagnetic calorimetry. The sensor consists of a matrix of 64x64 55um pixels, and provides a readout at 40MHz of the number of particles which have struck the matrix in the preceding 25ns. It can be configured to report this as a total sum across the sensor (equivalent to the pad of an analogue calorimeter) or the sum per column (equivalent to a traditional strip detector). Design and operation of the sensor is described, and the results of chip characterisation are reported and compared to simulations.
