摘要：
A 100 x 100 mm(2) 2D imaging detector, based on a triple-GEM gaseous multiplier, striped x-y readout anode and discrete delay-line readout, is presented. The fast (2.1 ns tap(-1)) delay-line circuit was designed to match the anode-charge signal profile, namely its rise-time and length. The detector's imaging capability was systematically studied in Ar/CO2 (70/30) with 5.9 keV X-rays; x-y resolution of sigma = 0.05 and 0.1 mm for top and bottom anode strips, respectively, and integral non-linearity of similar to0.15% are demonstrated.
