Title: Large Surface MicroMegas with Embedded Front-End Electronics for a Digital Hadronic Calorimeter
Abstract: In order to study the advantages of a digital hadronic calorimeter for particle flow algorithms, we aim to build a detector prototype with MicroMegas chambers. The bulk technology was chosen for its robustness and the possibility of industrial manufacturing process for mass production. First tests of 1 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> granularity MicroMegas with analog readout are very promising. Larger chambers with embedded digital front-end electronics together with detector interface readout boards are being designed. The challenge also lies in the mechanical design of a 1 m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> chamber with a total thickness of 6 mm.
