Abstract :
Two spectrometers, one on each extraction line of the SLC (Stanford Linear Collider), have been installed to momentum analyze each SLC beam pulse and determine the electron and positron beam energies. A method of determining and monitoring the absolute magnetic field strength for these dipoles has been developed. A total error on the magnetic field integral of δ∫Bdl/∫Bdl=1×10-4 has been achieved. The field integral can be monitored continuously during SLC beam operation using radiation-hardened equipment. The laboratory field mapping techniques and the field monitoring methods are described
