Description
The low-energy accelerator and experimental facilities at RAON are currently in operation following the completion of installation and initial alignment. Maintaining stable beam delivery requires periodic verification of beamline alignment accuracy relative to the facility's survey control network. This poster presents a geodetic alignment assessment of major RAON experimental beamlines, including the Cyclotron, ISOL, and CLaSsy sections, using laser tracker coordinate measurements. By comparing measured component positions against their nominal reference coordinates, alignment deviations were quantified and sections requiring correction were identified, followed by precision realignment of the affected components. A comparative analysis of beam transmission efficiency before and after realignment confirmed that improved geometric consistency with the survey control network substantially enhances beam transport performance.
