The HEPS storage ring consists of 48 7BA cells, with multipole magnets in each cell supported by several multipole girders. A set of alignment adjustment mechanism is present between each multipole magnet and the girder to fine-tune the magnet's six degrees of freedom position. The majority of magnet adjustment mechanism structures utilize vertical wedge blocks and horizontal and longitudinal...

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.

The storage ring of high energy photon source (HEPS) has about 1536 vacuum tubes, which need different supports to align them to the desired position and keep their stability. According to the operational requirements of the storage ring vacuum tubes, this article introduces several types support structure of vacuum tubes. And finite element thermal-stress analysis was conducted on the vacuum...

This paper presents a novel method for direct wire offset measurements using photogrammetry, with a focus on integrating a link to gravity. This development is motivated by the High Luminosity Large Hadron Collider (HL-LHC) project, where increased radiation in the Long Straight Section (LSS) necessitates automating the wire measurement process with a Full Remote Alignment System (FRAS). To...

Youen Delalande (Synchrotron SOLEIL)10/10/2024, 10:30
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...

Zihao Wang (Institute of High Energy Physics, Chinese Academy of Sciences (IHEP CAS))10/10/2024, 10:30
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...

SuperKEKB is a double ring collider consisting of a 7 GeV electron ring (HER) and a 4 GeV positron ring (LER) with a circumference of 3 km.
Go to contribution page
SuperKEKB was constructed by reusing the KEKB tunnel that was shut down in 2010. The KEKB beamline magnets were aligned in the same plane at the time of construction. SuperKEKB utilizes “nano-beam scheme,” where two low emittance beams collide with a... -
49. Status on geodetic studies and alignment perspectives for the CERN Future Circular Collider (P8)Witold Niewiem (CERN)10/10/2024, 10:30
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...

Martin Joska (European Spallation Source)10/10/2024, 10:30
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...
