Description
The beams in the LHC can be intercepted by many different types of
objects moving into the vacuum chambers. These include devices
designed for beam monitoring,machine protection and for data taking
by the experiments. Moving these objects can only be permitted under
certain conditions. Interlocks should prevent quenches or even
damage in case of wrong actions. A complete inventory of such
devices will be given along with the conditions under which they can
be moved and the interlocks,or signals, that are required to ensure
they cannot be activated at other times. A particular issue
concerns the optics imperfections which can change significantly
the safe position settings for a given mobile device. Controlling
the orbit and beta-beating errors is therefore an important pre-
requisite to commissioning protection devices and the collimation
system.
