The six kicker systems required for proton and pbar manipulations in the main ring and tevatron, associated with colliding beam operations, are illustrated schematically in Fig. 1. Functionally, these systems may be categorized as follows: 1) Proton targeting for pbar production at 120-150 gev: MR-E17-1 kicker at E17 in the main ring kicks the beam across the F17 Lambertson septum; 2) pbar injection from the accumulator at 8 gev: MR-E58 kicker at E48 in the main ring kicks the pbar beam injected at F17 onto the closed orbit; 3) Proton transfer from the main ring to the tevatron at 150 gev: MR-C48 kicker at C48 in the main ring at T-E17 kicker in the tevatron transfer through the Lambertsons at EO; 5) Proton abort at 150-1000 gev: T-B48 kicker at B48 in the tevatron kicks the proton beam across a Lambertson septum to the tevatron beam dump; 6) pbar abort at 150-1000 gev: T-C17 kicker at C17 in the tevatron kicks the pbar beam into a 3M steel dump located in the co straight section. In addition to these functions, systems 2, and 4 (the ones involving pbar manipulations) will need to be able to be operated in reverse with protons for commissioning. This means that system 2 will need to be able to extract 8 gev protons from the main ring to the accumulator, and system 4 will need to transfer protons from the tevatron to the main ring at 150 gev. System 3 and 5 already exist for fixed target operations. For completeness, some of their requirements for colliding beam operations will be specified here, in general, the existing hardware can handle the requirements. In addition to these kicker systems, a pulser (F17P) is also planned for use with the F17 extraction/injection magnets. The pulser will provide one cycle of A 14 Hz sine wave, at a repetition rate of 0.5 Hz. The use of a pulse for these magnets, rather than a ramped supply, has the dual advantages of substantial power savings during operation, and a reduction of the time during which perturbing fields will be present in the field-free Lambertson aperture, and the region near the c-magnets, through which the main ring beam passes during acceleration.
