The anode wire of traditional tissue equivalent proportional counter(TEPC)was replaced by GEM(gas electron multiplier)foil so that GEM-TEPC could be designed as a positionsensitive detector based on multi-signals readout electronics system(Fig.1).The sensitive volume of GEM-TEPC was divided into mini-multi-element.Two separated
