Popis: This paper presents the operational characteristics of several integrated Micromegas detectors. These detectors called InGrids are made by means of micro-electronic fabrication techniques. These techniques allow a large variety of detector geometry to be made and studied. Gain, gain homogeneity and energy resolution were measured for various amplification gap sizes, hole pitches and hole diameters in Argon/Isobutane. Gain measurements as a function of gap thickness are compared to the Rose and Korff formula and a model of the detector gain. Our model uses electric field maps and MAGBOLTZ calculated amplification coefficients.
