The Superconducting Super Collider (SSC) Low Energy Booster (LEB) is a synchrotron which accelerates bunches of protons from a momentum of 1.2 Gev/c at injection to a momentum of 12.0 Gev/c at extraction. The main bending dipoles with a peak field of 1.3 Tesla and the main focusing and defocusing quadrupoles with a peak gradient of about 14.9 Tesla/m operate on the same power supply which ramps up sinusoidally from a current of 10% of the peak value at injection to the peak at extraction in a 10 Hz cycle. The ratio of the quadrupole gradient to the dipole strength is kept sufficiently constant over the ramping cycle so as to avoid a tune shift. The magnets are also designed to achieve a prescribed field quality so as to minimize emittance growth during acceleration. This report describes the design of the LEB dipoles and quadrupoles.
