2. Mandate DESCRIPTION (Jan 2007)
The CLIC study is carrying out a number of specialized development programs of subsystems including high-power rf structures, micron precision pre-alignment, nanometer stabilization, beam instrumentation, active alignment and beam dynamics, vacuum etc. As these programs have advanced, an important priority is now to address the integration of the various subsystems into the CLIC module – the basic unit of hardware which will be repeated over ten thousand times along the length of CLIC. The module study raises feasibility issues, identifies areas needing study and design, addresses important aspects of cost and provides basic parameters for other areas of the study.
MAIN TASKS
Definition
Overall layout,
space hindrance,
number of components and their position
system integration (RF components, quadrupoles, alignment supporting, stabilization, cooling, vacuum, beam instrumentation..)
layout of special regions (drive beam turn-around loops),
Definition of the supporting system
Definition of the cooling system
