ALICE MONITORING

The ALICE Monitoring System (SMS) utilizes BCAMs and multiplexers to monitor the deformation of the Spaceframe rails and HCAL rails in the L3 magnet. Key components include various BCAM configurations on the baseplate and axial positions, ensuring a clear line of sight is maintained along the entire length of the rails. The total height of the monitoring system is approximately 80mm, with a maximum screw adjustment distance of 140mm. Proper space allocation as per the drawings is crucial for effective monitoring.
