Abstract

With the application of the twodimensional GEM gaseous detector in X ray imaging, the correction method of gain uniformity caused by tripleGEM avalanche structures and electric field uniformity should be studied. The paper reported the study of the tripleGEM detector with effective area 100 mm×100 mm used the Pad’s size of 9.5 mm×9.5 mm. In the test, 100 readout channels were designed. Results showed that gain remained stable over time; as air flow increases, gain from increases obviously to changes very little. Particularly, triple GEM’s gain uniformity was very good (more than 80%) and the range of energy resolution was from 0.18 to 0.22. To improve gain consistency of results, the difference value revised was obtained to be about 0.1 by the least square method. It provided a better method to improve gain uniformity of GEM detector.
