[en] The parameters of the dipole, quadrupole and sextupole magnets in the 10Hz Booster Synchrotron of the ESRF (European Synchrotron Radiation Facility) are detailed. A number of possible power supply systems are considered, and the advantages of the classical 'White Circuit' over other variants are presented. The paper then concentrates on the dipoles and quadrupoles, considering the interaction between the power supply and magnet design. The interaction of coil eddy current loss and magnet voltage is examined, and end 'roll off' geometries for both sets of magnets are presented
