Description
Since several years and following the ALARA recommendations, the SU team has developed specific systems to prevent its staff to be exposed to high radioactive doses when measuring the position or realigning some LHC components.
Around the low beta quadrupoles, a permanent monitoring system as well as a remote adjustment system have been developed allowing the measurements and the readjustment of these critical magnets from the SU staff offices. Also in the LSS7 of the LHC, the collimators can be surveyed from the surface using a dedicated train, circulating on the monorail, which can measured their positions with respect to the adjacent quadrupoles using the stretched wire and photogrammetric technology. Moreover a new project to measure remotely the position of the LHC components in the arcs is under development using the above mentioned technology as well as modular robotics.
The presentation will include the status of the already existing instrumentation as well as the future development and perspectives
