Measured longitudinal beam impedance of booster gradient magnets
The Booster gradient magnets have no vacuum pipe which forces the beam image current to flow along the laminated pole tips. Both D and F style magnets were measured with a stretched wire to determine the longitudinal beam impedance caused by these laminations. Results are compared to calculations done 30 years ago. The inductive part of the magnet impedance is interesting because it partially compensates for the negative inductance effects of space charge on the beam. An R/L circuit consisting of 37K{center_dot} in parallel with between 40 and 100uH is a reasonable approximation to the total impedance of Booster magnet laminations.
