Nuclear Instruments and Methods in Physics Research Section A: Accelerators …, 2002•ElsevierWe present a novel design for large-area gaseous detectors based on the MICROMEGAS
technology. This technology incorporates an insulating grid, sandwiched between the micro-
mesh and the anode-pad plane, which provides a uniform 200 μm amplification gap. The
uniformity of the amplification gap thickness has been verified. The gain performances of the
detector are presented and compared to the values obtained with detectors using cylindrical
micro spacers. The new design presents several technical and financial advantages.
