The precise survey and the alignment results of the J-PARC LINAC

J-PARC linear accelerator components have been installed. Before the beam commissioning, a precise survey for alignment has been performed. The reference points were set up on the tunnel wall to built a survey network. Based on the survey results, the magnets in the straight section were re-aligned finely. Then, the results of the displacement are confirmed to be tolerable for the beam commissioning.
