متن کاملDatum Definition Problems in Accelerator Alignment *
Any measurement task requires a fixed reference base (the datum’) from which measurements can be made and calculated. The linac was the datum to which all SLC components were aligned; although this reference existed as a physical object, the actual establishment of the datum and its transferral to datums that were more useful for the SLC installation challenged the technology and computational ...
