Results of Field Measurements for PETRA Magnets

PETRA consists of 232 dipoles, 300 quadrupoles and 152 sextupoles. The field integral for all dipoles as well as the multipole distribution of the field integral for all quadrupoles and sextupoles has been measured for different currents using fast automatic measuring machines. The results are collected in distributions showing the spread in the magnetic performance for each kind of magnet. Measurements of the hysteresis effects are shown, too.
