Development of a two-dimensional imaging GEM detector using the
resistive anode readout method with $6\times6$ cells
Abstract: We report the application of the resistive anode readout method on a two
dimensional imaging GEM detector. The resistive anode consists $6\times6$ cells
with the cell size $6~\mathrm{mm}\times6~\mathrm{mm}$. New electronics and DAQ
system are used to process the signals from 49 readout channels. The detector
has been tested by using the X-ray tube (8~keV). The spatial resolution of the
detector is about $103.46~\mathrm{{\mu}m}$ with the signal part
$66.41~\mathrm{{\mu}m}$. The nonlinearity of the detector is less than $0.5\%$.
A good two dimensional imaging capability is achieved as well. The performances
of the detector show the prospect of the resistive anode readout method for the
large readout area imaging detectors.
