The 1m3 Semidigital Hadronic Prototype
  A high granularity hadronic 1 m3 calorimeter prototype with semi-digital readout has been designed and built. This calorimeter has been made using stainless steel as absorber and Glass Resistive Plates Chambers (GRPC) as active medium, and read out through 1x1 cm2 pads. This prototype aims to demonstrate that this technology fulfills the physics requirements for future linear collider experiments, and also to test the feasibility of building a realistic detector, taking into account design aspects as for instance a fully embedded front-end electronics based on power pulsing system, a compact and self-supporting mechanical structure, one-side services...
