Calorimetry at future linear colliders could be based on a particle flow
approach where granularity is the key to high jet energy resolution. Among
different technologies, Micromegas chambers with 1 cm2 pad segmentation are
studied for the active medium of a hadronic calorimeter. A chamber of 1 m2 with
9216 channels read out by a low noise front-end ASIC called MICROROC has
recently been constructed and tested. Chamber design, ASIC circuitry and
preliminary test beam results are reported.
