In this study by N. Smirnov at Yale University, the relationship between MMG gain and voltage with various gas mixtures (Ar + isoButane + CF4, He + isoButane + CF4, Ne + isoButane + CF4) is explored for TPC with GridPix readout. The data reveals insights into the performance of the MMG mesh for different gas combinations. The images presented illustrate the gain measurements for each gas mixture, providing valuable information for experimental setups utilizing these configurations.
