Trends of accelerator components coordinates on the storage ring, which are designed as the SPring-8-II, are calculated with ground deformation growth rates. The rates are evaluated based on survey data measured since 1996 for the existing SPring-8 accelerator components. Next, alignment errors for all neighboring two magnet-girders are numerically estimated as relative error ellipses via a su ... More
