||The two apertures of the double bore magnets form two channels of the LHC. Each arc has one outer and one inner channel.
||The cold mass refers to the part of a magnet that needs to be cooled by the cryogenic system, i.e. the assembly of magnet coils, collars, iron yoke and Helium vessel.
||The two machine channels cross at the experimental insertions, i.e. at IP1, IP2, IP5 and IP8.
||Complete magnet system integrated into one cryostat, i.e. main magnet coils, collars and cryostat, correction magnets and powering circuits.
