First results on the characterization of new semitransparent amorphous silicon sensors

This paper presents the first results on the performance of a new generation of semitransparent amorphous silicon position detectors having very good properties, such as a spatial reconstruction precision better than 10 /spl mu/m, deflection angles smaller than 10 /spl mu/rad and transmission in the visible higher than 80%. In addition, the sensitive area is very large: 30/spl times/30 cm/sup 2/.
