Abstract :
Installation of a radiative-Bhabha luminosity monitor for CESR-c operation in 2004 required replacing a 40-mm-aperture steel quadrupole magnet with one of aperture 75 mm while maintaining field-quality tolerances at the level of a few parts in 104. We present the design methodology using 2D-and 3D-finite-element field calculations, discuss the fabrication and mechanical tolerances, and present the results of flip-coil field measurements.
