60. A Modular and Sustainable Software Ecosystem for High-Precision Survey and Alignment at CERN (THO04)

Francis Klumb (CERN)

Maintaining high-precision survey and alignment software at accelerator facilities is challenging due to small teams, regular staff turnover, and incoming engineers with limited domain or programming experience. At CERN, years of fragmented development had produced a heterogeneous survey software landscape, with several applications abandoned after their original developers left. The creation...

61. Hydrostatic Leveling Systems at the Advanced Photon Source (THO05)

Achieving and maintaining the alignment tolerances required for the upgraded Advanced Photon Source (APS) is a significant challenge, particularly in the presence of ground motion and settlement. To monitor vertical displacement and transfer elevation over long distances, two hydrostatic leveling systems (HLSs) are being deployed at APS.
The storage ring system consists of 105 HLS sensors...

62. FCC-ee MDI alignment monitoring mock up update (THO06)

Léonard WATRELOT (CERN)

The Future Circular Collider (FCC) is a proposed next-generation collider at CERN, intended to succeed the High-Luminosity upgrade of the LHC. A key element of this project is the Machine Detector Interface (MDI), which forms the link between the accelerator and the detector and fine-tunes the beams immediately before collision by optimizing beam parameters to maximize luminosity. To achieve...

The High Luminosity upgrade of the Large Hadron Col
lider (HL-LHC) project aims to increase the integrated lu
minosity by an order of magnitude over the LHC’s original
design specifications. To achieve this objective, strict control
of the alignment of the new Inner Triplet superconducting
magnets installed around the ATLAS and CMS interaction
points is essential. This is provided by the...
