Magnetic and mechanical axis of Short Straight Sections in the arcs: a summary of the results of the first 111 warm and cold series tests.

Abstract

This report contains a statistical summary of the results of the magnetic and mechanical alignment tests performed at CERN on the first 111 Short Straight Sections for the arcs. The measurements, obtained with different instruments, include the mechanical axis of the Cold Bore Tube at room temperature and the magnetic axis of main quadrupoles and correctors at both room and cryogenic temperature. The results show that both the accuracy of the instruments and the quality of the assemblies are, on average, well within the specifications
