Description
The KOMAC 100 MeV proton linear accelerator has been providing high-quality proton beams to users in various fields since 2013. KOMAC's facility consists of a 100 MeV linear accelerator, one 20 MeV general purpose beamline and five 100 MeV beamlines: a beamline for RI production, low-flux, general purpose, prototype RI beam production, and a test beamline. At KOMAC, alignment-related work is divided into two parts: alignment of accelerating machines and monitoring for accelerator building ground displacement. First, for the alignment of accelerating machines, the overall alignment work such as axis setting, arrangement of accelerating machines and alignment of accelerating machines according to the construction of the accelerator was carried out in the 2012-2013 period. The maintenance of the accelerator is performed every year due to DTQ failure of the DTL tank, and alignment work is also performed after improvement works such as adding an injector, expanding the beam lines, and installing the additional beam diagnosis devices. Second, HLS (Hydrostatic Leveling System) and WPS (Wire Positioning System), which are for monitoring the ground movement of the accelerator building, were installed as a follow-up measure to the earthquakes that occurred near KOMAC in 2016 and 2017. The sensors of HLS were installed in 10 locations throughout the accelerator tunnel where the accelerating machines are located, and the sensors of WPS were installed in 8 locations to monitor the movement of the basement surface according to the characteristics of the KOMAC accelerator building, in which one side of the building is a basement. In this paper, the overall contents related to the alignment of KOMAC 100MeV proton linac are presented.
