Accurate alignment of beam components in particle accelerators is crucial to optimize machine performance and enhance precision measurement in the experiments. CERN is developing a new process for calculating beam position offsets directly in the field during the alignment stage.
This process benefits from recent developments within CERN’s adjustment software, LGC (Logiciel Général de...
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) aims to enable continuous operation at instantaneous luminosities over double the current LHC value. To meet this goal, components installed in the Long Straight Sections around the ATLAS and CMS experiments must be aligned to within a tolerance of 0.45 mm vertically and 0.2 mm radially over a length of 420 meters. This precise...
Since 2020, we have been continuing to conduct control surveys of the KEK electron-positron accelerator using a laser tracker and digital level. Since analysis has confirmed a trend in beamline fluctuations, we introduce an attempt to experimentally introduce a crack displacement meter to confirm the trend in fluctuations.
Located in the heart of the Paris-Saclay university and technology park, SOLEIL is preparing a major upgrade of its machine and beamlines. This project known as SOLEIL II aims to provide a 4th generation synchrotron light source by the end of 2030. The new storage ring will have an emittance of 85 pm.rad which will naturally arise challenging questions about the solutions to be chosen for its...
The High Energy Photon Source (HEPS) has been under construction since 2019. It is designed to be the first high-energy diffraction-limited synchrotron light source in China. To achieve an ultra-low emittance of less than 60pm.rad, substantial efforts have been invested in the alignment process of the SR. This involves thousands of elements being arranged in a very tight space. To fulfill such...
Recent progress of the SHINE(Shanghai Hard X-ray FEL Facility)
The ongoing feasibility study for the Future Circular Collider (FCC-ee) planned to be built at CERN raises survey and geodetic challenges. Developing an alignment strategy for the 8832 magnets within the 91.2 km circular tunnel, associated transfer lines, and the 2 or 4 experiments is critical. A robust geodetic infrastructure, including the definition of coordinate reference systems and the...
The objective of the Shenzhen Superconducting Soft-X-ray Free Electron Laser (S³FEL) is to develop a free electron laser source utilizing a superconducting linear accelerator operating at an electron energy of 2.5GeV. The facility has a length of approximately 1.8km and features a wavelength range of 1 to 30nm for its Free Electron Laser, aimed at advancing cutting-edge scientific research and...
At the European Spallation Source (ESS), we extensively use Spatial Analyzer (SA) for a variety of applications, including network calculations. A significant challenge has been to involve local gravity observations during the network calculation in SA. To address this, we have developed a solution to represent the local geoid within SA. In this poster we will present our methodology and...
