ABSTRACT
The Fermilab Booster is a rapid-cycling, 15Hz, alternating gradient synchrotron with a radius of 75.47 meters. The lattice consists of 96 combined function magnets in 24 periods, with nominal horizontal and vertical tunes of 6.7 and 6.8 respectively. The Booster accelerates protons from a kinetic energy of 400 MeV to 8 GeV. at a harmonic number h=84. using 17 rf cavities with frequency which slews between 37.7 MHz (at injection.) and 52.8 MHz (at extraction). The revolution time at injection is 2.2 f1 s. A comprehensive technical description of the Booster as built can be found in reference 13]. The injection system utilizes the Hcharge-exchange injection technique [2]. The typicallinac peak-current is 45 rnA; usually up to ten turns of H-beam are injected in the booster. The injected beam is a stream of bunches equally spaced at the linac rf frequency of 201.2 MHz. During injection. a pulsed orbit bump magnet system (ORBUMP) is used to superimpose the trajectories of the circulating (protons) and injected (H-) beams.
