Abstract :
This paper investigated the influence of GEM detector gain on the spatial resolution of a GEM-TPC prototype. Tests show that the x-resolution of the TPC prototype improves with the increase of the voltage of GEM readout detector. The change tendencies of the effective number of electron and the relative gain match quite well.
