✦ Synopsis

The deterioration of the sensitivity of amorphous silicon strip photo detectors ('ALMY' sensors) under long-term illumination has been studied with collimated laser beams of different wavelengths and intensities. The high position sensitivity of the ALMY sensors allows for the precise localization of the illumination point and for monitoring of the local sensitivity degradation with respect to the rest of the non-illuminated sensor area.
