Abstract :
Final results of magnetic measurements of 128 quadrupoles and 32 sextupoles are presented. There are many places in the SHR complex where these magnets will be operated from a common power supply. For the quadrupole magnets there are 4 octets, 4 triplets and 18 doublets; these magnets have been matched to ±0.1% in excitation response for the operating range corresponding to 0.3-1.0 GeV. For the sextupoles there are four octets where the (pairwise) matching has generally been made to the ±0.3% level. Parameterization of the data as well as fits are described and examples of the magnet groupings are shown
