Performance test of the CMS link alignment system

摘要

A first global test of the CMS Alignment System was performed at the 14 hall of the CERN ISR tunnel. Positions of the network, reproducing a set of points in the CMS detector monitored by the Link System, were reconstructed and compared to survey measurements. Spatial and angular reconstruction precisions reached in the present experimental set-up are already close to the CMS requirements. (C) 2002 Elsevier Science B.V. All rights reserved. References: 10
