A large size prototype of a TPC with GEM amplification has been successfully built and operated. To obtain an active area larger that the one provided by one GEM foil, for the first time 2 independent GEM towers have been hosted on a single pad plane, taking care of minimizing the dead space. The readout structure has been inserted in the former HARP TPC installation, which provides an excellent test-bed for TPC R&D activities. Data in different conditions of gas, magnetic and drift fields have been collected and analyzed.



We will first review the motivations and present status of the R&D activities towards micro-pattern amplification TPCs. We will then present motivation, design, construction and operation of the prototype. Possible additional R&D activities will also be discussed.
