The Extremely Brilliant Source (EBS) Project successfully greatly improved the brightness of the ESRF X-ray source by replacing the existing machine with a new machine with a much more compact lattice. This paper will discuss alignment related aspects of the assembly, installation and commissioning of the new ESRF EBS machine. It will concentrate on techniques used, results achieved and the...
During the long shutdown for maintenance and upgrade, (LS2 2018-2021) the CERN injector complex received an important update to meet the future HL-LHC requirements.
One major project was the construction and installation of a new beam dump in the Super Proton Synchrotron (SPS), able to cope with the increasing brightness of the High-Luminosity beams. The challenge for survey engineers was to...
A precise survey was completed in 1998 for the Main Injector using ten concrete monuments and ten sight riser drop points which were incorporated into a network to provide absolute positioning for the tunnel control system constraints at the +/- 1mm level. The 8Gev Injection tunnel network was tied to the Main Injector network and the surface network using four sight riser drop points. The...
