Abstract
The CLIC module, about 2 m long, is composed of the drive
beam and the main beam modules. Considering 26 sectors per linac and
knowing that each sector is about 800 m long, we count more than 10000
modules per linac. The drive beam module comprises 4 decelerating
structures and two quadrupoles forming a FODO cell. Each decelerating
structure powers two accelerating structures. Since the beam has to be
focused, some accelerating structures are removed at regular intervals
to liberate space for a quadrupole of a FODO lattice.
The layout of the standard and special modules is presented as well as
the general system integration. Preliminary values on pre-alignment and
beam-based alignment tolerances are also given. The last part of the
presentation will be then dedicated to the beam layout configuration.
