The objectives of the PACMAN project are to improve the precision and accuracy of the alignment of accelerator components. Two steps of alignment are concerned: the fiducialisation, e.g. the determination of the reference axis of components w.r.t. alignment targets, and the initial alignment of components on a common support assembly. The main accelerator components considered for the study...
The CLIC two beam module will be described together with its numerous alignment constraints and tolerances dictated by beam dynamics. A pre-alignment of the a high number of comments of the order of 10 microns has to be realised for the CLIC project. In this sense the CLIC project represents a new level of requirements to accelerator alignment. The CLIC alignment strategy will be described and...
A hadron collider of 100 km circumference and 100 TeV in the center of mass is under study by the international physics community as next energy frontier Future Circular Collider (FCC). The same tunnel could host first a lepton collider, FCC-e+e−, with beam energy ranging between 45 and 175 GeV. For attaining luminosities between 10^34 and 10^36 cm^-2s^-1, the beams must be strongly focused at...
