Abstract: The basic principles and implementation of onedimensional position encoding readout for MICROMEGAS have been introduced in this paper. A 10 cm×10 cm prototype of onedimensional position encoding readout electrode based on printed circuit board was designed. Preliminary test indicates that the induction readout is feasible and the ideal charge distribution is 1∶2. X rays emitted from 55Fe source were collimated to one of strips on the readout electrode through a slit of 200 μm, position decoding well reproduced the position of the 55Fe source. For its limitations, we have proposed a onedimensional grouped position encoding readout technique to address a neighboring strips simultaneously fired situation. The amount of readout electronics is very easy to approach a obduction of 75% with position encoding read out technology.
