Resumo(s)
The “CMS Safety Closing Sensors System” (SCSS, or CSS for brevity) is a remote
monitoring system design to control safety clearance and tight mechanical movements
of parts of the CMS detector, especially during CMS assembly phases. We present the
different systems that makes SCSS: its sensor technologies, the readout system, the data
acquisition and control software. We also report on calibration and installation details,
which determine the resolution and limits of the system.
We present as well our experience from the operation of the system and the analysis of the
data collected since 2008. Special emphasis is given to study positioning reproducibility
during detector assembly and understanding how the magnetic fields influence the
detector structure.
