Alignment of detectors at CERES/NA45

Creators

Description

The note is addressed to the problem of alignment (accurate positioning) of Silicon Drift Detectors (SDD) within Silicon Vertex Telescope (SVT) system and alignment influence on the matching quality at CERES. The fast algorithm for determination of the misalignment parameters of SDD within SVT and entire SVT with respect to PAD-chamber was proposed and approved for the model data and data ensembles of 1995 and 1996. The results show good precision of obtained parameters. In the future this approach can be applied for the alignment with data obtained from TPC
