Extraction system design for the SSC Low Energy Booster

The Low Energy Booster (LEB) is the first of 3 booster synchrotrons of the SSC accelerator complex. It will accelerate protons from an injection momentum of 1.22 GeV/c to a final momentum of 12 GeV/c, cycling at a frequency of 10 Hz. A single-turn, vertical extraction system has been designed to extract the proton beam from the LEB within the possible machine operation tune range. At extraction, a set of five bump dipoles will be used to vertically displace the central orbit by approximately 1.5 cm at the entrance of the first septum magnet. A fast, ferrite kicker will be used to sweep the proton beam past the septa to initiate the extraction process. The physics parameters and the preliminary designs for the LEB extraction elements are also given
