Description
After LS1, radiation levels in collimation areas (mainly IR3 and IR7) will rise to levels that will require long decay times before interventions by humans. Collimators have been designed not to be serviced in situ but rather to be easily exchangeable, therefore in case of serious issues with a collimator the LHC will be stopped for the replacement of the faulty collimator.
In accordance with the ALARA principle, remote techniques will be used by EN-HE in collaboration with EN-STI to exchange collimators with the benefits of reduced radiation exposure of personnel and increased LHC availability.
The presentation will describe one of the projects in the scope of this work - the specification, design and construction of a custom-built remotely operated crane-vehicle to remotely handle and transport collimators in the LHC tunnel. The vehicle itself and the organisation of its operation will be presented.
