Abstract

The minimum unit geometric model of signal GEM(Gas Electron Multiplier) detector has been build, and the Maxwell v11 program is used to calculate the electric potential, electric field, potential value of triangular meshes of detector, and the hemitropic faces and electric field intensity vector graphs can be drawn at the same time; Then the calculated result is imported into Garfield program, and simulate the avalanche drift process of single electron and multiple electrons under the role of electric field by Garfield program. In addition, the gas effective gain that varies with the change of the proportion of mixed gas, collecting field, drift field, GEM membrane electrode voltages are also be simulated and discussed.
