Survey and alignment data analysis for the ALS storage ring
The survey and alignment effort for the Advanced Light Source (ALS) accelerator complex has been described elsewhere. Data analysis for this task comprises the creation of ideal data, comparison of measured coordinates with ideal ones, and computation of alignment values, taking into account the effects caused by finite observation accuracy. A novel approach has been taken, using personal computer spreadsheets rather than more conventional programming methods. This approach was induced by the necessities to create and frequently refine the analysis procedures while measurements were already underway, and further by hardware constraints that limited the use of an available surveying code. A major benefit consists in the ability to identify and deal with discrepancies that occasionally arise when different techniques are used to observe the same object, in a timely and efficient manner. As a result of the performed survey and alignment work, the ALS lattice magnets have been positioned with accuracies well exceeding the original specifications.
