Alignment of components at the University of Maryland Electron Ring

Alignment of experimental components is critical to operation of The University of Maryland Electron Ring (UMER). Procedures and equipment used to align components of the electron ring are presented. The compact nature of UMER (ring diameter/spl ap/4 m) presents unique challenges and advantages associated with the placement of vacuum components, confinement and steering magnets, and diagnostic equipment. Alignment of all components has been accomplished with a set of two T3000 theodolites and a three-dimensional software package from the Leica Corporation. A set of fiducial monuments has been used to establish a permanent coordinate system. The position of UMER components has been measured to an accuracy of less than 100 microns in that coordinate system.
