In this work we present a novel idea for a compact spark-protected single amplification Micro-Pattern Gas Detector (MPGD). The detector amplification stage, realized with a very similar to a GEM foil, is embedded through a resistive layer in the readout board. cathode electrode, defining the gas conversion/drift gap, completes the detector mechanics. The structure, that we call micro-Resistive WELL (-RWELL), has some characteristics in common previous MPGDs, such as C. A. T. and WELL, developed more than ten years ago. The object of the present study has been realized in the 2009 by TE-MPE-EM Workshop at. The new architecture is a very compact MPGD, robust against discharges and exhibiting a gain (6103), simple to construct and easy for engineering and then suitable for large area devices as well as huge calorimetric apparata.
