Description
The LHC complex is divided into a number of zones with different levels of access
controls. Inside the interlocked areas, the personnel protection is ensured by the
LHC Access System. The system is made of two parts: the LHC Access Safety System and
the LHC Access Control System. During machine operation, the LHC Access Safety System
ensures the collective protection of the personnel against the radiation hazards
arising from the operation of the accelerator by interlocking the LHC key safety
elements. When the beams are off, the LHC Access Control System regulates the access
to the accelerator and its many subsystems. It allows a remote, local or automatic
operation of the access control equipment which verifies and identifies all users
entering the controlled areas.
The global architecture of the LHC Access System is now designed and is being
validated to ensure that it meets the safety requirements for operation of the LHC. A
pilot installation will be tested in the summer 2005 to validate the concept with the
users. In addition the pilot installation will permit the resolution of any
integration and performance issues related to the numerous sub-systems.
On the LHC Access Safety side, the technical specification is now completed, the
hardware and software architecture has been defined; a call for tender has been
issued for the LASS programming and installation tasks.
The identification of the LHC machine elements that have to be interlocked with LASS
has also been completed.
