Abstract
A design for a gaseous radiation detector based on charge multiplication is described and its performance assessed. The device uses a microstructure which has an anode surrounded by another close-lying second anode, playing the role of a grid at a potential between anode and cathode that allows a more accurate definition of the multiplication volume. The main characteristics of this gridded microstrip gas chamber (G-MSGC) detector are described. The best energy resolutions for 5.9 keV X-rays obtained were 13.4% for Xe and 12.6% for the P10 mixture.
