    "abstract": "We present an original design for large area gaseous detectors based on the\nMICROMEGAS technology. This technology incorporates an insulating grid,\nsandwiched between the micro-mesh and the anode-pad plane, which provides an\nuniform 200 $\\mu$m amplification gap. The uniformity of the amplification gap\nthickness has been verified under several experimental conditions. The gain\nperformances of the detector are presented and compared to the values obtained\nwith detectors using cylindrical micro spacers. The new design presents several\ntechnical and financial advantages.",
