Description
A high precision alignment system has been developed for online monitoring of the tracking detectors of HERMES. The system consists of a He Ne laser, Fresnel zone plates, CCD cameras, and electronics to read out the image. It records the alignment information of each detector automatically every 30 min during the experiment. The relative detector positions can be monitored with a precision of better than ±60 μm (1σ).
